Abstract
This research examines the effect of design modifications on response of sandwich plates to impulse pressure loads. The objective is to limit damage by delamination of the laminated face sheets and by crushing of the structural foam core that dominates response of conventionally designed sandwich plates. This is achieved by introducing structural elements that store the incident energy and thus reduce damage-related energy dissipation. In particular, ductile interlayers inserted between the outer face sheet and the foam core, can absorb a significant part of the incident energy, and protect the foam core from excessive deformation. These design concepts have been developed in our earlier work on the effect of low and medium velocity impact on sandwich plates, where they enhanced resistance to local deflections of the face sheet, foam crushing and interface delaminations.
