a question about UMAT

[snowden]

Dear Jorgen:

can you tell me if we can see UMAT code of the constitutive model in ABAQUS?

THANK YOU

[Jorgen]

Hello Snowden,

What constitutive model are you interested in? and what are you trying to model?

Dear Dr. Jorgen:

Thank you replying to me.

I want to model soft soil. I think, for soft soil only elastic-viscoplastic model can simulate it best. At the same time, no much work has not been done in the past. So I think new results are expected to be achieve. Of course, it is not easy.

Hello Dr. Jorgen,

I am working on soil material modeling. I am refering to your thesis and papers for this purpose. Would it be possible to see the Bergstrom-Boyce (BB) model UMAT code in Abaqus?

Thank you very much.

I cannot share the source code for my implemention of the BB-model.
I can answer specific questions that you may have, though.
