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

Digimat-CAE/Abaqus/CAE

• Digimat-FE uses Abaqus/CAE to generate the RVE mesh and the Finite Element model that is then solved with Abaqus/Standard. Post processing results is done in both Abaqus/CAE and in Digimat-FE in a complementary way.
• A plug-in interface enables Abaqus/CAE users to:

- Select a DIGIMAT materialor import it from the Digimat-MX database.
- Prepare the DIGIMAT user material for the coupled analysis by defining the orientation file and all integration parameters.
- Update the Abaqus input deck with the defined DIGIMAT user material.
- Rename the SDVs.
- Extract the strain state of a single element and apply it as the boundary condition on a RVE analysis model generated in Digimat-FE.

Digimat-CAE/Abaqus/Standard

• This interface is used to model the thermo-mechanical behavior of composites structures under quasi-static and dynamic loading conditions. In these applications the material can be modeled as anisotropic thermo-elastic, elasto-plastic (with damage), viscoelastic, elasto-viscoplastic, viscoelastic-viscoplastic, hyperelastic or defined with a Leonov-EGP model.

• Temperatures or residual stresses coming from injection simulation can be used as inputs to the coupled FE computation.

Digimat-CAE/Abaqus/Explicit

• This interface is used to model the impact and failure behavior of composite structures. In such applications, anisotropic elasto-plastic, viscoelastic, elasto-viscoplastic or even viscoelastic-viscoplastic material responses can be modeled. 
• It provides an accurate failure prediction: 

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

• Residual stresses coming from injection simulation can be used as inputs to the coupled FE computation.

• We believe in the incorporation of fiber orientation from flow simulations into a structural simulation package like Abaqus. DIGIMAT is the absolute front runner in that. It is not only a trend but an absolute necessity to make simulations of intrinsically anisotropic material like glass fiber reinforced thermoplastics more realistic and to increase their predictive power, Dr. H. van Melick, Global CAE manager, DSM Engineering Plastics
