Résumé

3D damage analysis of low-velocity, low-energy impact on laminated composites by damage mechanics. When subjected to low-velocity impacts, the high damage sensitivity of carbon-epoxy laminated composites results in localized damage, mainly transverse cracks and delamination. To be able to assess the critical nature of the induced damage, a thorough description of damage mechanisms is of primary importance. The challenge here is predicting the initiation and the propagation of low-velocity impact induced damage by using damage mechanics. Therefore, a mechanical and numerical model of the damage occuring in laminates, previously defined at LMT, is updated to this specific type of loading. Preliminary results show a good correlation with accurate experimental measures
