摘要：

This paper discusses the investigation of the transverse impact of plate-like composite specimens. It focuses on the initiation of delaminations at matrix cracks and on the interaction of delaminations with matrix cracks. This study shows that an accurate prediction of the development of matrix cracks and delaminations during impact requires the use of energy criteria, taking into account the appropriate fracture toughness values, depending on the interface and the mixed mode loading. Also, the accumulation of damage in the plate has to be taken into account when predicting the damage development. (C) 1996 Elsevier Science Limited
