Hi,
I am trying to create a material model in Abaqus such that I have a varying yield strength through the depth (y-coordinate). I want a model which has maximum yield strength at the top surface and gradually goes on decreasing with y-coordinate. Is there a way to do this? Any help/insight would be greatly appreciated. Thank you.
Regards,
Deepak Patil

Hi all,
I am using Abaqus to simulate the behavior of a steel connection using a Static,General analysis. For bolts, the last values for yield stress and plastic strain are 1 and 0.05, respectively.After running the model, I get values of equivalent plastic strain in the bolts of 0.15.
Why do I get values that are higher than the ones I define? Shouldn't I get a maximum of 0.05? What can I be doing wrong?
Thank's,

We are seeking to hire outstanding candidates for a post-doctoral research position in
the Koslowski’s group at Purdue University to work on dislocation dynamics and/or
continuum modeling of plasticity. The project involves developing and applying
numerical methods to study creep and plastic deformation in nano and ultrafine
crystalline materials. Successful candidates will have the opportunity to interact with a
wide range of experimentalists and theoreticians in academia, industry and national labs.
Hello All,
I have a question regarding Ansys solution divergence in nonlinear static analysis, with geometry and material nonlinearities. In this case the model is shell but that should ba valid for bricks as well.
