Overview

Digimat lets engineers do both micro- and macro-scale analyses of composites, predicting how they will perform and calculating their mechanical, thermal and electrical properties for use in all sorts of downstream FEA analyses.

Engineers typically start modeling by gathering material information and strand orientation data from Moldflow, 3D-Sigma, Moldex3D, Simpoe or another injection molding simulation solution, in the case of molded materials. Digimat-MAP calculates residual stresses and temperature from the injection molding mesh and defines an ideal structural FEA mesh. From here, many users go straight to FEA - MSC Nastran and Marc for instance, and other solvers that have direct interfaces. They may also use Digimat's MF, MX, FE modules to look at test data for the composite and its constituents and look at promising material candidates. Users are able to see the tight link between part geometry, material flow during manufacturing and the resulting fiber orientation and the effect all of this has on the part's ultimate mechanical behavior.

Digimat-MF

Digimat-MF is the Mean-Field homogenization module of Digimat which offers the capability to define the local material behavior as a function of the material behavior of:

  1. the matrix and inclusion phases;
  2. the composite microstructure morphology (inclusions weight, shape and size).
Digimat-MF is a user-friendly micromechanical material modeling software where the user inputs the material behavior of the phases, the microstructure description and the loading applied to the resulting multi-phase material, guided by a tree data structure.

Digimat-FE

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.

Digimat-MX

Digimat-MX is a composite materials database giving access to experimental data at different strain rates, temperatures and so on. It contains Digimat material files already reverse engineered based on experimental data. This software clearly helps sharing data between stakeholders or simply internally in a company. It provides optimization tools to perform parameters identification and to reverse engineer easily and efficiently Digimat material models for a whole of material range.

Digimat-Map

Digimat-MAP is a 3D mapping software used to transfer fiber orientation, residual stresses and temperature from the injection molding mesh to the optimal structural FEA mesh.

Digimat-MAP is fully integrated within Digimat's multi-scale modeling process. Digimat-MAP is an accurate, efficient, robust and flexible software tool used to transfer the fiber orientation, residual stresses and temperature between dissimilar injection molding and structural analysis meshes where they can be used by Digimat-MF to FEA interfaces (ANSYS, LS-DYNA, Abaqus, PAM-CRASH, SAMCEF...) to perform state-of-the-art nonlinear multi-scale analysis.

Micross

Micross is a multi-scale tool for the modeling of bending and in plane shear tests of sandwich panels. It is a complete, simple, accurate and flexible software tool.

Micross takes into account the effect of the microstructure for both the core and the skins of the sandwich:

  • For the honeycomb core, the homogenized properties are computed by Micross based on the geometry of the unit cell of the honeycomb.;
  • For the skins the same choice is available. A skin is made of several layers piled up in a given order, with given orientations and thickness. Each layer can be defined at the macro or micro level. In this last case, Digimat-MF is used to compute the macroscopic stiffness properties of the layer based on the description of its microstructure.
