Digimat-MF is the Mean-Field homogenization software used to predict the nonlinear constitutive behavior of multi-phase composite materials.

Product description

Digimat-MF is the Mean-Field homogenization module of Digimat which offers the capability to define the local material behavior as a function of the material behavior of:

1. the matrix and inclusion phases
2. the composite microstructure morphology (inclusions weight, shape and size)

Digimat-MF is a user-friendly micromechanical material modeling software where the user inputs the material behavior of the phases, the microstructure description and the loading applied to the resulting multi-phase material, guided by a tree data structure.
