Digimat-CAE/Marc is an interface strongly coupling the Digimat-MF technology with the Marc finite element solver via the user defined material card of Marc. e-Xstream innovates by offering state-of-the-art micro-mechanical tools accounting for the local microstructure of composite materials. Indeed, composites are no longer defined at the macroscopic scale but are instead defined at the constituent level along with microstructural information. Based on the constituents’ definitions and using homogenization tools, Digimat computes any local composite anisotropic responses.
Such approach enables to bridge the gap between the manufacturing process and the structural performances of parts. For instance, fiber orientation computed when simulating the manufacturing process can be given as an input to the structural simulation and serves Digimat at computing accurately the local properties of the composite material based on the local orientation of the fibers.
Digimat offers a wide variety of material models to capture nonlinear, strain-rate dependent and thermal dependent effects. It also offers state-of-the-art failure models which can be defined both at the composite and at the constituent scales.
The Digimat interface to Marc is provided as a software library which is compiled by the users to couple the two products. The coupling is such that Digimat computes the local anisotropic responses for each integration point of the model, at each time step, of the finite element Marc simulation.
