Hypermesh Composite Tutorial [Ply-Laminate Structure]
Vložit
- čas přidán 14. 08. 2024
- In this tutorial, we will create a composite material consisting of ply-laminate structure using Hypermesh. The process of creating composite materials is explained in detail.
This type of composite materials is widely used in automobile and aerospace industry for design of high performance-low weight components. Hypermesh has many advanced options to create and visualize such composites.

This channel is GOD-tier . please never stop uploading as the quality and information you are producing now is second to none. i watch your videos after going through the altair training material and it works like magic. Thank you and waiting for more.
Thanks a lot for the kind words! Im glad my videos are helping you.
Very detailed and systematic explanation for the subject,
Thank you!
Excellent Explaination.......Hats Off
Thank you :)
Great explanations on creating the laminate structure. I like how you specified the significance of the element normal, material orientation and ply directions especially when you deal with orthotropic material definitions. You can also set the composite failure criteria (i.e., Tsai-Hill theory) to post-process the result with a scale of 0 to 1. It's unfortunate that the hyperview doesn't support the detailed element representation yet (i.e., shell elements to detailed 3D shape with the specified thicknesses), it would be nice to collect the stress contour for all the plies for comparison. I remember asking about this few years ago to Altair but it doesn't seem to be updated yet.
Thanks Ken!
Yeah, 2D element post-processing in Hyperview is definitely below par. I wish they roll out a feature by which we can visualize all the plies at the same time in Hyperview.
I would like to discuss more about this failure criteria with you. Will get in touch soon!
Thanks very much for the video! Very helpful!
Could I ask you , whether there is any 'contact' between the layers when you create a multi-layer material model like this?
Hi there,
This method of composite modeling creates a bonded laminate from a stack of plies. It cannot predict debonding. It is only applicable to linear analysis, hence no contacts are involved.
I hope this helps!
Hello Sir,
First of all thanks for so many informative videos! Sir can you please make a video for a 4 Point bending analysis for a Honeycomb Sandwich Plate in Hyperworks. I am having trouble running analysis.
It would help me a lot for my project thesis.
Thanks a lot!
Thank you
May I know the difference between angle value given in PLY dialog and material orientation coordinate.
In material orientation, if I orient x in a different way and then give the angle, it will take angle from that x direction?
Do we have natural fibers like abaca or sisal for defining the elements????
As of now, in its standalone state, Optistruct only supports modelling of ply-laminate composites. Fiber reinforced composites are not supported.
However, if you link Altair Multiscale Design Modeler with Optistruct, you can model woven fabrics as well as reinforced polymers!
Good date to you sir i have plat composite unidierectional with fibre orientation 50° and i want to determinante the young module Ex and Ey in 50° from simulation
Hi,
Can you do 3 point bending test on honey comb composite structure in Radioss. I need some help in that. please do some vedio on it. it will be a great help.
sir please tell how to solve static structural analysis of composites using PCOMP and PCOMPG card
Please watch the composite analysis video from 'Optistruct Tutorials' playlist to learn more about this.
I did a divinycell and fiber carbon laminated airplane fuselage for an aeromodel, applied PCOMPP as the property but the CFailure on the analysis shows 0 for max and minimum for every ply, could you help me? Maybe i can send you an email if you can help me
Hi Arthur,
For better communication, please send an email. The contact details are provided in the 'About' section of this channel.
Thanks.
@@Aeroswap please suggest any book for finding Material Properties.
How to model honey comb pannel with top and bottom skin in hypermesh
bro can you explain assigning ply with the hyperlaminate and pcomp and pcompg card images
Thanks for the suggestion. I will work on this topic soon!
Hello, Aeroswap. I watch this video and this make me understand the step very clear. Thank you so much for making a good tutorial. But i have a question, if the composite that we use is the woven glass fiber, will the method that we need to create each ply will be different? Because in this video we have one orientation in each ply but woven, there’s 2 orientation in each ply not unidirectional like this tutorial. Do you know how to deal with this? Thank you in advance.
Great Tutorial and great explanations!! Do you have this kind of composite material creation for Radioss as well? Thank you.
You are saving my life! Hahahah this tutorial is amazing! Do you know if there is a way to simulate a ply of carbon fiber's plain weave?
Good to know it was helpful !
I dont think it is possible to model that in Optistruct. In its standalone state, Optistruct does not support reinforced composite modeling (Only ply-laminates can be created).
To do that, the Multiscale modeler tool needs to be used in link with Optistruct!
you can model a weave as two UD laminates stacked on top of each other with half thickness
That is a nice idea! It might work 👍🏻
Please make a video about bullet impact on composite laminate
Hey Preeti, I am planning a video about this. Will be released soon 👍🏻
thanks, great help. However, how to know the orientation degree for each ply. Is there any standard?
The details of the ply-layup have to be acquired from the composite data sheet. Many times, this information is not easily available.
When to use PCOMG card image
How to setup a ply orientation and thickness in model browser? So that I can use them later on in Hyperstudy.
Please help!
Hi, very good video, thanks!
I have a 2 questions, it will be very hopeful if you can help me with it:
1. For laminates, you can create a layers of the material defined in property, using HyperLaminate instead of using ply and Laminate. But how to visualise the layers of the material in HyperMesh (like you did in this vide)? If I’m good understanding, this is different approach to create a laminates but I’m not fully understanding it.
2. I discovered that in new versions of HyperMesh, possible is to create laminates using solid elements. PCOMPLS properties is made for this. Do you know how to properly create the model, consist solid elements and using PCOMPLS properly to set up a composite layers material? And visualise it?
Thanks in advance!
Hello Aeroswap,
I'm following your exact steps, but I am using Abaqus as my solver (so there is no PCOMPP Property or MAT8 materials). Everything works perfectly fine, I can even visualize all my plies and the fiber orientations. But when I try to solve it in Abaqus it always says that there are element with missing properties, even if there are clearly not because I assign my propertie to all components of my part just as you do in your video. Do you have any workaround for that?
Best regards, nice videos!
Hey!
I am not used to working with Abaqus. Most of my work is related to Optistruct. I do not know about the specific difference in modelling of composites for Abaqus.
Nevertheless, I will try to find a solution for this. I will get back to you soon if I find something worthwhile.
PS : Im glad you liked my videos! Thanks for watching 👍🏻
@@Aeroswap Thanks alot for your effort, i really appreciate it!
Hi bro, I'm working on composite analysis but I'm using PCOMP Card image in my property but after complete final boundary I'm facing with the error can you please suggest me how to over come this and my error is.....
*** ERROR # 622 ***
PLY 1 does not contain any valid plate elements referencing a
PCOMPP card.
Please use PCOMPP instead of PCOMP. It is much easier to model composites with PCOMPP.
Hey Swapnil,
Do you know if We can have the constraint in each ply ?
Best
Harry
Do you mean the constraint we use in optimization setup? If yes, it is possible.
What are the default units u have considering while giving input for those properties?.. Like youngs modulus and density?
It is kN, GPa, mm, ms. You can use any consistent unit system as per your requirement.
@@Aeroswap .. Thank you for quick reply.. Hope we will see one video on bullet impact on composite plate. Eagerly waiting for that
Please tell how to export this composite laminate in LSDyna for explicit analysis.
Make sure you are setting the user profile to LS Dyna before starting the composite modeling.
After the setup is done, use the export solver deck option to save a 'K' file. Then you can run it using LS Dyna solver.
@@Aeroswap but after starting work with user profile of LSdyna I am facing difficulty while aloting material props. Why so?
Right, composite modeling setup is very different for every solver. The process shown in this video is only for Optistruct. You might have to refer some other tutorial to learn composite setup for LS Dyna.
Sir, please make a video about Composite optimization in optistruct.
Thx!
Good suggestion! I will work on it soon 👍🏻
Hello Aeroswap,
I’ve watched the tutorials video that related to modelling composite in your CZcams channel. It’s great tutorial, make me understand easier and faster. But I’ve never seen the topic about modelling the adhesive layers in composite laminate. Do you have experience for that? I’ve struggled with this step for 2 weeks. I am doing my work in Radioss solver.
Best regards,
I think you are referring to Cohesive Zone Modelling (CZM). That sort of analysis is quite advanced and difficult to perform. I will try to work on this topic soon. Thanks for the suggestion!
@@Aeroswap Thank you so much. I will look forward to seeing this tutorial from you.
I don't understand what's E1 and E2 and how to calculate them or do we have any chart for different composites?
Please help
These values are aquired from online material databases. You will find detailed material property values for several composite materials that can be used readily.
@@Aeroswap can you please share a link for the database from which you pick values. I have been searching online and didn't find anything which tells E1, E2 and NU12.
@@Aeroswap Hey aeroswap, I am getting an error "Draping stopped, maximum shear exceeded". Can you please tell me what am I doing wrong?
Hiii can u share link for property assigning in hypermesh for boron epoxy
Can you please specify a way to change the element normals ? Like if they are not in the required direction
You can use the 'reverse' and 'adjust' options provided in the element normals panel to switch normal directions.
Just select the required elements and make necessary changes.
@@Aeroswap Thank you very much 😃. Your channel is amazing pleas keep on posting such tutorials 👏👍
Nice explanation but while creating laminate I don't get the dialogue box to define laminate
I am using 2020 version
Try creating the plies and laminate directly from Model browser. The modeling process is different in older versions of Hypermesh.
Sir can this method be used for any imported geometry?
Yes, you can. Just make sure the material and fiber orientations are properly assigned to get accurate results.
Sir, Please upload a video explaining Fatigue Analysis in Optistruct.....Thank You!!
Will work on it soon! 👍🏻
Also dude make one on CFD tetra meshing
Okay!
