The problem considered in the example is a 3D version of the verification test case VM296 in the Ansys Mechanical APDL Verification Manual.

The bilinear isotropic hardening plastic material with temperature-dependent yield stress and tangent modulus is defined using the TB,USER model. The linear thermal material is defined using TB,USER,,,THERM. The source files for the UserMat.F and UserMatTH.F subroutines used in this example can be found in subdirectory: /ansys_inc/v242/ansys/customize/user/ (Linux) or Program Files\ANSYS Inc\V242\ansys\customize\user\ (Windows).

The model is discretized using SOLID226 elements.

Results are expected to agree closely with the results of a 2D simulation (VM296) performed for simulation time = 13 s.
