Combined loadings after medium velocity impact on large CFRP laminated plates: Discrete ply model simulations

To decrease development costs of aeronautical composite structures, industrials and academic researchers are turning to “virtual testing” methods. To help achieve this objective, a new methodology has been developed at the Institut Clément Ader. It is based on a complex loading test rig for technolo...
