Open-Hole tensile test for CFRP materials (Airbus Test Method AITM 1-0007)

Prediction of the failure envelope of unidirectional composite materials by means of finite element simulations

Enhancement of Digimat-FE, an existing commercial software product, to make such predictions available to industry

Enhancement of Digimat-FE to extend these capabilities to more complex composites such as 3D woven composites

Coupling of Digimat-FE with LS-Dyna, a commercial finite element package, to use the latter as finite element solver to make stiffness predictions
