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

DIGIMAT is a powerful tool that is giving us a new insight into our composite polymers. Its ability to model thermal expansion as a function of temperature, for instance, has been instrumental in understanding some subtle mechanism of warpage of injection molded parts.

Integrated crash pads allow weight and cost reductions. Setting the absorption behavior is only possible through a rigorous composite modeling. An integrated structural analysis with DIGIMAT clearly reveals those benefits.Sandro Wartzack, Head of Simulation, Brose
