More than 50% of e-Xstream’s software and services revenues are generated in the plastics industry. Our material and industry expertise added to the DIGIMAT technology allow us to address any plastic parts suppliers needs in material modeling.
- DIGIMAT nonlinear multi-scale material and structure modeling platform is used to model thermoplastics (e.g. PA, PP, PC, POM, PPA, …) and thermosets (Epoxy, Polyurethane, …) reinforced with short, long or continuous glass and/or carbon fibers as well as any type of micro or nano size fillers (glass beads, talc, …).

DIGIMAT-MF is used as a “numerical material lab machine” to predict the thermo mechanical properties (E, CTE, Stress-strain curve,…) of a reinforced plastic “material point” that is equivalent to a material test sample like an ASTM tension test dumble. It uses Eshelby’s Mean Filed homogenization methods to model a plastic matrix assumed to behave as a linear, nonlinear and rate-dependent material models, reinforced with any number of linear or nonlinear inclusion phase like a fibers, fillers or other polymer phase.
-
DIGIMAT to CAE stands for DIGIMAT interfaces to injection molding (Moldflow, Moldex3D, Sogmasoft) and structural FEA software (ANSYS, LS-DYNA, Abaqus, PAM-CRASH) that allow accurate modeling of warpage, vibration, stiffness, creep, relaxation and strength of plastic parts subject to quasi-static or crash type of loading conditions by taking into account the fiber orientation, residual stresses and temperature induced by the injection molding process.
- MAP is a shell and 3D mapping software used to map fiber orientation, residual stresses and temperature from injection molding mesh to the structural FEA mesh.
