cratepy.material.materialmodeling

Constitutive modeling of CRVE material clusters and homogenization.

This module includes the class that contains the data associated with the CRVE’s material clusters constitutive state and homogenized strain and stress tensors, as well as the required methods to perform the material clusters constitutive state update, the computation of the material clusters consistent tangent modulus, and the computational homogenization of the material clusters strain and stress tensors.
