Digimat-FE is used to generate a realistic Representative Volume Element (RVE) of large variety of material microstructures (plastics, rubbers, metals, graphite, ...). Digimat-FE allows to describe the microstructure of your composite as well as the material properties of its constituents in order to generate the FE model of the composite’s RVE.

Digimat-FE uses Abaqus/CAE to generate the microstructure mesh and the actual finite element model that is then solved with Abaqus/Standard. Model post processing is then done in Abaqus/CAE and DIGIMAT.

• Definition of multi-phase composite microstructures made of: spheroids, platelets, ellipsoids, cylinders, prisms, polyhedrons made of 20 faces (icosahedrons), any shape defined in a geometry file
• Definition of constituents material behavior: elastic, thermo elastic, viscoelastic, hyperelastic, elastoplastic.

• Definition of inclusion phases involving : volume or mass content, inclusion size or number of inclusion used to generate the RVE, size distribution, fixed, random or orientation defined by an orientation tensor, clustering, coating.

• Strain based and mixed (strain/stress) loading definition

• Export of RVE geometry in .STEP, .IGES, .BREP formats

• Export geometry and model definition to Abaqus/CAE

• Export geometry to ANSYS Workbench

• Interface to ABAQUS/CAE allows:

            - automatic import of the RVE geometry, per phase material properties and boundary
              conditions
            - automatic meshing and job creation
            - post-processing of per-phase fields (stress, strain, …)

• Digimat-FE allows a user friendly generation and analysis of cemented carbide RVEs and serves as a platform for virtual material development to enhance the interpretation of simulation results, Michael Magin, Application Engineer Manager, Ceratizit Luxembourg
