This tutorial is very useful! I have learned about how to use umat in ABAQUS. Many thanks!

Hi, thank you for the tutorial. I have a question about the Datum of the Model. Is there a way to change the position of the coordinate system to be in middle center of the part?

When using the UMAT subroutine related to elastic-plastic constitutive, the analysis step is dynamically implicit or statically universal？

Thank you for the very nice tutorial. Would you mind sharing the UMAT file or telling us where we can find it? Thank you in advance.

Dear Sir,

Thanks for this video. I will be pleased if you can provide me with UAMP Subroutines.
Takns in advance !!!

hello sir, when testing a single element how much displacement has to be applied. suppose i am taking a element of 0.5 mm x0.5 mm x 0.5 mm how much displacement has to be applied.

can you share UMAT subroutine? That will help in trying it out

I am getting "there is zero force everywhere in the model" the model is not converging. what might cause the error?
