How do I model an Anisotropic Nonlinear Elastic Model for Tensile/Compression Simulation?

Please login with a confirmed email address before reporting spam

Using COMSOL Multiphysics, I am aiming to model and simulate the compression and tensile test scenarios of 3D printed samples (ABS, PLA, PETG). However, it would appear that the default equations used for the Nonlinear Elastic Material section of the the Solid Mechanics Physics model is Isotropic. I would like to use an Anisotropic approach given how the printing parameters in the lab would change the samples' outcome from an Isotropic to an Anisotropic material.

Any advice would be greatly appreciated. I've attached a snap shot of the compression model along with the equations involved for the Nonlinear Elastic Material
