DIG120/DIG201/DIG202 - Digimat Standard Training

This course is to teach how to use a Digimat material model in a FE analysis of a composite part that has fiber orientations predicted by an injection modeling or draping simulation. By using a Digimat material model in a structural analysis users can take into account the non-linear material properties of composites and the effects of the local microstructure on their part.

Length: 
2 days + 1 optional day
Pre-requisites : 
Basic theoretical knowledge of material constitutive model (elasticity, elasto-plasticity) is advised. Good knowledge of one FEA code is mandatory.
Topics: 
  • Technical information on the way the program operates, e.g. licensing, file organization,...
  • Introduction to designing RVE (representative volume element) for various composite microstructures including composites with; multiple reinforcing phases, clustering, and decohesion zones, among others, using Digimat-FE
  • Introduction to the Digimat Graphical User Interface including the plug-in embedded in CAE codes (Menta, Abaqus, Ansys, HyperMesh).
  • Mean-field homogenization theory as well as the material models available in Digimat-MF.
  • Material database management and automatic calibration of Digimat materials.
  • Coupling of Digimat with FEA code in Digimat-CAE. Introduction to the different solution procedure (macro, hybrid, micro) and presentation of the failure criteria definition.
  • Mapping of fiber orientation tensors, initial stresses/temperatures between two dissimilar meshes in Digimat-Map. Theoretical aspects of the mapping procedure are explained.
  • Exporting the RVE into Abaqus or Ansys to run a finite element analysis on the material and post-processing of the results in Digimat-FE.
  • Guided exercises to implement the different procedures presented during the course.
