Digimat-CAE/Pam-crash is the interface that strongly couples Digimat-MF to PAM-CRASH via the USER DEFINED MATERIAL capability. Digimat-MF is provided as a software library that is linked to PAM-CRASH to offer a strong multi-scale coupling between the nonlinear micromechanical material modeling capabilities of Digimat-MF and the nonlinear explicit
FEA capabilities of PAM-CRASH. In this configuration, Digimat-MF acts as an advanced anisotropic, nonlinear and rate-dependent user defined material at each relevant integration point of PAM-CRASH FE mesh.

• Accurate Failure Prediction:

- Micro (matrix and/or fibers) & macro failure indicators.
- Failure indicators can be strain rate dependent.

• Accurate Micromechanical Material Modeling:

- Anisotropic: dependent on the microstructure morphology.
- Nonlinear: elasto-plastic, with possibly continuous damage.
- Strain rate dependent: viscoelastic, elasto-viscoplastic and viscoelastic-viscoplastic matrix.
- Temperature dependent:thermoelastic materials.

• Accurate Nonlinear Multi-Scale Structure Modeling:

- Heterogeneous material: Anisotropic properties are a function of the local microstructure morphology.

• Efficient & User Friendly Solution Procedure:

- Streamlined multi-scale modeling procedure.
- Intuitive graphical user interface.
