Some issues concerning the dynamic response and damage of composite laminates subjected to low velocity impact
Abstract. This thesis presents a discussion on a few specific topics regarding the low velocity impact behaviour of laminated composites. These topics were chosen because of their significance as well as the relatively limited attention received so far by the scientific community. The first issue …
