You can compute stress-strain curves for RVEs with nonlinear constituent materials, simulating uniaxial tension, uniaxial compression, and shear test cases. Both hyperelastic and elasto-plastic material models are supported for the constituents. This document explains how to use the nonlinear material properties, which are provided in the 2024 R2 release as a Beta feature. See Material Designer Options in the Material Designer User's Guide for information about how to activate Material Designer Beta features.
