Digimat predicts the linear and nonlinear mechanical behavior of multi-phase materials such as Polymer Matrix Composites (PMC), Metal Matrix Composites (MMC), Ceramic Matrix Composites (CMC), etc.

Mechanical properties for Material Engineering applications

Material engineering applications involving mechanical material properties rely on two tools: Digimat-MF and Digimat-FE.

Specific capabilities have also been developed to model woven composite (2D, 2.5D and 2D braided).

Digimat-MF to simulate mechanical performances of composite materials

For all types of composite material, mechanical performances like
  • Stiffness
  • Creep and relaxation
  • Strength and durability
are computed by Digimat-MF by using the Mean-Field homogenization technique.

This technology predicts in a very fast way:

  • the stress-strain curve of the composite
  • the creep and relaxation behavior of the composite
  • the average stress and average strain in each constituent of the composite
  • the strength of the composite

Thanks to its ease of use, Digimat-MF constitutes as a virtual laboratory where a large number of materials can be tested in a very short period of time. The design of a composite material can then be optimized to reach specific targets. Viscous effects and coatings can also be taken into account.

Digimat-FE to simulate mechanical performances of composite materials

A more in-depth analysis of the behavior of your composite can be performed in Digimat-FE. In this tool, the complete stress and strain distribution inside your composite material can be investigated. Effects like decohesion at the fiber-matrix interface and clustering can be studied. Dedicated statistical tools are available to post-process the FE results to take smart decisions on the improvement of the design of your material.

“The application of Digimat-MF and Digimat-FE paved the way for me to give an insight into the influence of microstructure on the overall mechanical and brittle damage behavior of highly porous sound absorbing ceramics. I was able to contribute to the improvement of material strength by new material design while keeping the good sound absorption."
