FEM: user material subroutines (UMAT in ABAQUS), mechanics

Posted 9 years ago

Hi dear community,

just a quick question (mainly for those who are also familiar with ABAQUS or other comparable FEM programs and non-linear modelling of mechanical behavior, e.g., plasticity). Is there any module in the FEM environment in Mathematica in which you can set a general material behavior like in the UMATs of ABAQUS? I am just thinking of a standard von Mises plasticity model with ideal plastic behavior and homogeneous isotropic elastic behavior for small deformations. Or would you just write the evolution equations of the state variables in the field equations for the FEM solver and that's it?

Thank you!
