This video shows how Abaqus uses plastic material properties, plot stress vs strain curve in Abaqus visualization, understand restart analysis and visualizing the results such as rendering shell thickness in the viewport.
New Topics Covered in this Tutorial:
Model/Preprocessing
-Understand how Abaqus uses platstic material properties
-Read material data from an external file
-Plot a stress vs plastic strain curve in abaqus to visualize your own data
-Understand restart analyses request appropriate restart data
-create a new model to continue an analysis using restart data
-Create a new model to continue an analysis using restart data
-Use the load manager to enable/disable loads at a particular step
Results / Post-Processing
-Change viewport annotation optics to control the font size and style of legend block and state block
-Create new visualization viewports and tile them
-Use the frame selector tool to display specific frames
-Render shell thickness in the viewport
Fast Forward:
00:18 - Overview
4:01 - Part 1, Understand Material Plasticity and Restart Analysis
22:57 - Part 2, Create a New Model to Continue an Analysis Using Restart Data

Great job
Excellent tutorial !!! Thanks for sharing
Plz provide any video link for the elastoplastic bilinear material model.
plz, provide a video link for the elastoplastic bilinear material model.
Very informal and useful tutorial. Many thanks!!!
yes, you're right. Like your tutorials
I'm working on the detection of springback in v bending in 2D abaqus. But when I define true stress- true strain graphs for plasticty in a few lines in the material definition, the results of the springback are less than the experiment. But if I define only the line where the plastic strain is 0 (the first line (yield point)) the spring-back estimation gets much closer to the experimental results. Is it a correct method to define only the line where the plastic strain is 0? Do you have any other suggestions or is it enough to use this single line?
The experiment does not belong to me, I cannot reach the result for the material properties. I get the material information from the literature.
when defining the plastic strain in abaqus you have to calculate it as following:
plastic strain= total strain - elastic strain
for all point, so it is obvious that at yield point the plastic strain equal to zero.
go to this video its very obvious and helpful:

Hello Team SIMULIA. Thank you for making informative videos. I would like to point out that at the timestamp 10:09, stress and strain are denoted, these are interchanged. It may cause confusion.
I understand that today it is possible to joint two odb files in only one (concatenation). Could you explain that?
.res file does not work for parallel cpus. Do you have any suggestions?
Hi. thanks for your useful videos. but it isn't complete.... u didn't mention whether the plate is (2D Planar) or (3D Shell)?
Hi, do you know how can I calculate the yield load?
it is very useful video like others. I have one problem with restart commands. i have dome dynamic explicit analyses in the first model and want to do dynamic implicit analyses in the restart model, but dynamic implicit model is nor present in the step with re-start command. what should i do? it will be very helpful if you upload a small video on this or provide material.
hey, just seeing where you got the plastic data from?

Can we change material property in second step?
i have the same question

Dear Please I would like to ask if you have a tutorial video for using abaqus to make a 3D model to simulate pile -soil interaction and develop negative skin friction in details and calculate the value of the pore water pressure - drag load - soil and pile settlement and the values of the negative skin friction stress. If you have such tutorial please I need it for my research. thanks

30:39 in your results 3.08 e 8 was the value for max von mises and your highest value in palstic properties was 3.8 e 8 ... so is that fine I mean they are pretty close as you said earlier in the video ?

The merge of the two .odb would have been useful to illustrate.
