- ANSYS Workbench Tutorial using Explicit Dynamics to model a RC Beam (Reinforced Concrete Beam). Failed elements or cracked and crushed elements are deleted from the model as the analysis is running. Deformation of the Rebar is also shown. This is a high impact test of concrete. I will create a standard beam test video in the future for low speed cracking and crushing of the rc beam in ansys workbench.

@@drdalyo Thank you! Your videos are life saving, thank you so much. I never though someone was going to see this lol
+DrDalyO thanks a lot for the video, I am eagerly waiting for your waiting on the analysis of RC Beam in Static structural. In that video can you please explain how to create bond between steel and concrete, and how to input compressive strength of concrete from lab to be included in the concrete material thats' going to used in the analysis.
I hope you will consider this request and upload a video related to that....as soon as possible,
You're the best
Hey DrDalyo
these videos are great and you really helped me to learn ANSYS
Thank You so much
+amirmohammad rahimizadeh thanks for watching!
how to add steel fibres in concrete instead of steel bars?
How did you select velocity of 8000mm/s if we want to do for other materials how do you select the velocity for that material
+DrDalyO We here at university really learn alot from you. Specially the small small points u clarified during tutorials. Thanks. Great work
Thank you for this tutorial! But my problem is, how can I determine the max displacement and max loading that the beam can carry before its failure? Because this video didn't cover this kind of problem. Please, if there's anyone who can help me with this problem, it would be much appreciated!
It really helps a lot !!! Thank you for all the effort you've done to this tutorial.

thanks for the very informative video, please keep uploading more videos, you gave a long break, for example bird strike with ls dyna would be very beneficial
I love explicit videos.
Keep it up.
very informative and clear for a beginner like me to learn. Thank you

@@bonjoebeebello2560 for that you simulate problem at 3-4 different loading conditions and compare the results with safety factor.
Our technology can dramatically improve the efficacy of Ansys's output where multi-phase multi-scale materials like concrete are involved.
Great video. Thanka for posting this video
Welcome!!
Thank you very much for this tutorial
+Aqil Mousa thanks for watching!
Thank you! you really save my life!
very complete tutorial, thank you!
Sir, it is very useful and Informative..Kindly send more detailed video in solution set up.
Hello DrDalyo.
Great video, easy to understand. I like it. Thanks for sharing. Would you mind to share video on composites material like e-glass fibre laminated with epoxy resin or similar. Would be great if we can show the stress analysis or deformation if any.
+Tanie Lakibul Ibno It wasnt on my list of videos to do, but if other subscribers want the same thing, i could make one no problem! Thanks for watching
Is it possible to use explicit dynamics to simulate the crush analysis of cylindrical shell made of e-glass & metal sheet composites?
+Tanie Lakibul Ibno I am not so familiar with these materials, but I believe it should be possible. here is a soda crush can which is most probably out of cylindrical shell elements (czcams.com/video/dKtF1dg1BgI/video.html) as for the material, i assume you could assign anything you want in the engineering data.
Good idea, this video might help. Thanks for your suggestion.
Hello there! Your video has been really helpful for me and I have a question. Will the reinforcement setting work for a geometry which was created in Solidworks or does it need to be a line body? I am working on a model of a unit cell made of epoxy reinforced with graphene sheets. Thank you in advance.
Thank you very much! well explained!
I modelled my reinforcements in spaceclaim as solids but I'm unable to create a body interaction for the reinforcement. If I select other types like frictionless, bonded and frictional. That will work. Only reinforcement is unable to work. What do I do please.
I made the drawing in Fusion 360 and exported it as iges file. And when I tried applying the Body Interaction - Reinforment; it just highlights the all bodies yellow and the interaction remains undefined Could you please tell me, what mistake did I make.? Please need your kind support.
amazing video ..... and great presentation... !!!
great video presentation. thanks.
Awesome video! Thank you!
DearDr
Please tell me how to use explicit dynamic for solving static cases, what are the required settings for this case?
By other meaning if I have RC beam and I deifne the materials in explicit dynamic as built in concrete in explicit module like Conc 35 Pa and NL steel and the beam exposed to static loads, please tell me how to use explicit dynamic solver to solve this case, thanks
owl good tutorial! I just think the loading speed is a little bit high thus the deformation in midspan is relatively huge than prediction
thanks for your video
Welcome Lee!
It's really good example.I am want some example of nonlinear design of masonry building.
Many Thanks!
Daşşaanı yerim çoğiyi vidyo olmuş
Thank you so much. This is very beneficial tutorial for me.
Is it possible to plot a graph for example one axis is displacement at any point, the other axis is the force at any point any direction?
Yes is is possible. you can use the node selection to select a node and get displacement for it, then select both the force and the displacement results using the CTRL key and selecting the chart tool to plot the graph results.
@DrDalyO: Thank you so much for this video. Its greatly helpful. Hey, I have a question though, can I change the velocity to 125 m/s and run the analysis. Is there any other changes that I should be doing other than changing the velocity? I reduced the velocity and ran the analysis, its giving some weird results.
request to upload slab design of slab with deflection graph
1. How can I define the yield strength of structural steel?
2. How can I draw stirrup with different diameter with main rebar? The program always make them be one line (with the same diameter)?
Thank you
Does the punch stop eventually? In my computation it moves uniformly till the end of computation as if it's infinitely massive.
But I want to check if beam will break or not.
OK, I found it i needed velocity in INITIAL CONDITIONS.
thank for you, you are good teacher!!!
o It's Amazing video
Thank you for a wonderful video
but I have small question. How to Draw a reinforcement like stirrups reinforcement in concrete beams?
Thanks
+hayder khalid You could draw two lines one along the x axis and another connected to it on the y axis, then add a radius to it to make it like a stirrup. maybe check out some other videos on youtube for geometry modeler techniques, could help you in drawing line sketches.
at 15:07 from model we can see maximum total deformation is 1.1971 mm but in graph it shows total deformation value is 18.366 mm at time 5.0003e-3. How could we conform about maximum total deformation? Please help me to understand.
Thank you
problems
In the process of build the model for the analysis of the static , I did not succeed in a new bonding process between concrete and reinforcement , Although the use of the Command method in the code, the same problem was encountered in the analysis of Dynamic Transit
But the fatigue did not work for me and I did not know the use where there is an icon but when choosing the whole model shows a line while when
choosing the steel beam Appear result but how to verify it
I use ansys 18.2 which is better analysis dynamic transient structure or explicit dynamics
wouldn't a perfect plastic material static structural model make more sense for limit state design of a brittle material?
thank you so much
Thank you for this tutorial! But my problem is, how can I determine the max displacement and max loading that the beam can carry before its failure? Because this video didn't cover this kind of problem. Please, if there's anyone who can help me with this problem, it would be much appreciated!
Your video has been helpful but i have an error concerning the solver output it says "An error occurred when the post processor attempted to load a specific result. Please review all messages."
how do i solve this problem?
What are your computer specs? As I know you can use GPU only if it a Quadro or Tesla. I have GTX 1050 4G ...does it works? and if I have 6 cores, is it wise to use all of them? it will not supercharge the computer?
Ya probably wont work. There is a list of supported cards on the ansys website. Ya it uses multicores! I have an i7 9th gen 6core
@@drdalyo Thank you! Well done videos!
I created my own geometry myself in inventor, then I imported it to the Ansys. but in the connection -> Body interaction I couldn't choose reinforcement type? what's wrong.
Very impressive and informative
While you input the engineering data, you say that you choose the material from the list of explicit material, because you use explicit solver.
Is this general information? Namely if we use Steady-State Thermal, must we use Thermal Materials?
+Bahadır Gürbüz you dont have to, but yes, if your doing a thermal analysis, better to start with the thermal material database. But you can always customize your own material, but ansys gives you a good start with their identified databases
+DrDalyO Thank you very much for reply.
1. Can we take same result by using Static Stractural modulus?
2. If we want to see whether an aluminium alloy will be failure under any load, which material datas do we need to make come true this?
If in place of velocity I use displacement for compression of hollow tube along it's axis what steps do I have to follow. Plz recommende static structural or explicit vl be best for it.
Hello sir, I have a question following this video. I drew the line and create the cross-section in the geometry (SpaceClaim) as reinforcement in the beam, but the result show that those lines are not connected with each other. So can you tell me how to connect those lines (Stirrup in geometry) together? I couldn't figure it out but to ask you for help, please!
Thank you for making one of the few tutorials on damage/explicit modeling in ANSYS.
I have a questions though:
Do I need to use explicit solver for a tensile failure, too? If yes, how should I define the failure in Ansys? (in abaqus, there are many different ways that I could not find equivalent ones for them in Ansys)
I don't see there is any other way to delete element in the mechanical solver. Is it possible for you to make a tutorial on the failure/fracture of the materials? This is I believe one thing we need the most on CZcams.
This is really helpful. I have question tho. When it comes to adjust to visible, why does the results are changed when we activate 'adjust to visible'? I found out that numbers next to color distribution bar are changed. I'd really appreciate if you could explain it to me.
Please tell me how to fix this error.."AN unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes".
Thank you Mr Dalyo, that was really impressive for your didatic skills. If I want to simulate a breaking of something like a PCB, should I use explicit dynamics or statics structural? Because the load is applied slowly, but in static structural I get only infinite deformation. Thanks.
+Gabriel Moraes Barros if your doing drop tests lets say, thats explicit dynamics.
hi, my model is R.C. barrier wall on concrete support please my question that can i use support meshing different than the model above it and the nodes of support are not identical with the R.C. Wall nodes at contact area
How can I input commands for solid 65 and link 180 elements to concrete and rebars respectively in ansys explicit dynamics? Like, in static structural, we can do insert > command for the geometries.
Hello, I am trying to do thermal analysis of an RC beam in steady state thermal but I am having issues because the nodes of the beam don't intersect that of the concrete. Please can you help me as there is no body interaction (for the reinforcement) in steady state thermal. Thank you
I wonder if you could please make a video on a steel connection, which include all typical elements such as bolts, welds, plate, supporting and supported member ?
+Tien Cuong This would be an advanced video, im still doing begineer/intermediate. please check my other video in static structural for more information, its new! czcams.com/video/h2BApwflt3E/video.html
DrDalyO maybe you should consider commercialise an Ansys course on Udemy.com, your course would be very popular, and I'd be one of the first students :)
These video are great and I need a analysis of shearwall in ansys
Thanx sir for posting this video. I have one doubt. When i am checking the stresses in the deformed reinforcement its showing zero throughout the length. Please tell me i am doing wrong.
DrDalyO is a very cool video, you are the best, thank you very much. I try to repeat in version 2020 R2, but it does not work, because does not switch to beam mode. By right-clicking on the geometry from the option to replace the geometry, only "browse" is offered. You have an opportunity to prompt how to set the beam mode. Thank you in advance.
Hi can you show us how we can do the simuliation of the bond b/w concrete and steel reiforcing
very nice video i want to make a strain gauge like geometry can you have some video
Hi, DrDalyo,
this is very promising video on Reinforced Concrete beam Problem.
Do you have any idea how to construct the concrete beam with homogeneous material without using link 8 element in ANSYS.
The rebars material need to be added without using Link8 elements,
As per the description of ANSYS help in solid65 element model we can add three rebars materials.
I need to simulate the rebars without using Link8 element,
Can you help with this problem
can you please add the CFRP sheet affect in addition to the reinforcement bars .. I really looked up for this in CZcams .. all are using ansys APDL for this issue .. I need to do a project and I have already installed ansys WB on my laptop.. I really appreciate your help
thank you for the video. Can you do a video on elastic wave propagation in pipe or plate in Explicit Dynamics, that would be very helpful as there is no video available on this topic in Ansys workbench
just started studying the ansys, so a really problebli dumb question, no need for adding the earth gravity speed?
Good point. If I did not include it then technically it should be included. I thonk however it may not have such a big effect on results since the timeframe of the analysis is so short. You can try it and let me know the difference! Great question!
PLEASE UPLOAD VIDEO ON BULLET PENETRATION IN AUTODYNE.
Dear Dr. Dalyo, I am new to ANSYS Workbench software and I will like to have clarity on the concrete code. In the static structure, are the stress and strain data constant?
I tried to do like that test but I couldn't it. I think the reason of the failing is that I want to assign orthotropic material to the solid body but I don't know how to set the analysis settings of the explicit when I use like that type material. If you know that, please type me. Thank you so much.
Can you please help me with generating crack for 3 point loading beam case using polypropylene concrete
Thanks for sharing this important topic, this resolve some issue related to RC beam.
but I perform the same step but didn`t getting the same deformation in steel bar...and Sir I want to solve the one problem that is some kind of interaction between 2 solid body and which is in contact with each other some interface that interface is having some material properties..
can you highlight some guidance on this..
thanks.......
hi, thanks a lot for video its very helpful I did the geometry by own dimension andI did what u did exactly but after solving there is no deformation in the beam its not response for the force I don't know what the wrong it will be great if u reply me and if u you have similar video for static load can u provide it
+Ahmed Al-dean I plan on posting the static version by next week.
+DrDalyO Thank u so much for this really helpful video. I am waiting for static stractural version also thank you so much.
+DrDalyO Waiting for static structural as well. Thank you for great videos!
please see my new video!
Please add a video for non-linear buckling analysis of RCC beam....!
sir i am using ansys 12.0 and i cannot load your geometry file it shows error that says could not attach becoz it does not have any elements when i open the file nothing is there it looks like a new undrawn file please help me to get rid of this thing
+shanmugam sudhagar its probably because your using an older version of ansys. Check my tutorials start with ansys version 15 and up.
Which is better to use ansys workbench or ansys apdl for composite steel beam with slab reinforcment concrete under fatigue
dynamic loads
thanks
Could you please show how we can assign steel fibres into concrete properties to analyze how the fibre itself can effectively increase the shear resistance
+Fahad AlZahrani in an upcoming video
Hey man I'm confused for the brake pads hitting the brake discs... Will that be an explicit dynamics?? I can't categorize this!!... Can you make a video on this simulation?
Hell DrDalyO, I have invalid results. my Hourglass energy is too high as well. Pls how do I resolve the invalid results issue? Thank you.
Very nice clip. But can you tell please, how can i introduce and analyze deformed rebar in RCC beams????
Nice and most useful video, sir. How can this software downloaded? Is it free, or do I have to purchase it?
Dear DrDalyO,
Many thanks for your helpful tutorials, i did a model from scratch but it is saying that i need almost 300 hrs to solve it with the same configuration you did in here. ive downloaded your model from here and it was 6 minutes only, do you have any idea where did i get it wrong or how to enhance the analysis timings. (BTW I dont have any warning messages)
Thank you in Advance for your great help
connection between concrete and steel connection is very important, Could we know how can we do this connection in explicit Dynamics mode?
+AYDIN KICI please see my other video in Static Structural czcams.com/video/h2BApwflt3E/video.html
You're amazing! Thanks heaps!
awesome video🔥🔥🔥🔥
hello Daylo, Good information on explict dynamics. Could you please tell me how to add new materials like kevlar and other composite materials
this is so helpful thank u
Can you please explain something about the solver control, I cannot a sense even in a single parameter in ssolver controls.
thanks a lot
+DrDalyO can you make video on retrofitting of column (or beam)
Im not sure if it can be done in workbench or if it has to be done in mechanical APDL
How pin support will added in a beam at some distance of edge of beam....plz say
how to convert the concrete material from ansys(solid 65) or ls-dyna or ansys autodyn to workbench
Hi sir,
Thanks a lot for this tutorial, I'm doing a drop test on concrete specimen, can u plz tell me how to find No. Of steps taken for first crack and final crack,.. please guide me..
Thank you
plz make a video on how to draw a stirrups in static structural claerly explain this
Their is deformation in the reinforcement but no stress. Can you tell me how can I get stresses in reinforecement ?
Hello Dr.Dalyo Great video
I like the Video
I'm Work ''Static Structural'' but i am cannot find connection between concrete and reinforced. How can i connecting between
?both of them
+Hayder Ali Hi, as i mentioned in the video a few times, the analysis is only for the Explicit Dynamics module. To do a Static Structural analysis of concrete is actually very different unfortunately. It involves using command objects in order to use APDL commands to join the link elements to the concrete which is not as easy. I will post a video on Concrete RC Beam in Static Structural in the future. You could subscribe to my channel, and when the video is out you will get the notification!
Thanks!
where i can find in ANSYS Workbench elements known from APDL like RBE2 or RBE3? I would be very grateful for showing/writing the path to find it :)
best regards
Sir, SN curve of concrete for the fatigue analysis is present in ANSYS software or not if it have then please make video on SN curve of concrete
Thank you for sharing this :)
hey very helpful video ...I am working on some other geometry ...I want to export my results to LS DYNA code in ANSYS ...n see the simulations there in DyNA how to export that
Hi,
I need the geometry file. However, I can not download it. Please help me in this regard.
hi, your video tutorialis helpfull! could you help me, iam modeling rc beam with static structural analysis, but the rebar dont move after solve. just the beam have a displacement,. what is wrong with my model? it will be great if you reply my question. and i'll be waiting you concrete rc beam in static structural tutorial
+Laksemana Dewi you have to join the nodes of the link elements with the concrete elements. if not then thats exactly what you will get, the concrete moving but not the beams. Please wait for my RC Beam video on static structural
is it possible to do a repeated impact analysis using explicit, if yes how we can take the affect in picture after each impact
