Using Mathematica to Automatically Generate Abaqus User Material Subroutines

It is often difficult for commercial finite element (FE) analysis developers to implement highly specialized materials. Therefore, it is advantageous to allow users to code subroutines for specialized constitutive equations. The disadvantage is that the user must learn and understand the developer’s implementation of the nonlinear FE formulation. It is therefore beneficial to develop a process which can reduce the complexity of writing specialized material subroutines by generating the code automatically.
