Shock and Impact Response of Naval Composite Structures

Abstract

Analytical solutions for the impact and blast response of naval composite structures were developed in this research grant. Finite element analysis using ABAQUS and experimental results found in the open literature were also considered in conjunction with the work. Four problems, in particular, were addressed during the course of this grant period. These were as follows: (1) low velocity impact of a sandwich panel with Coremat(trade mark), a high impact resistant core, (2) blast response of a composite sandwich panel with traditional PVC foam cores; (3) high velocity impact and perforation of a composite sandwich panel again with traditional PVC foam cores; and (4) implosion of a laminated composite cylinder under external blast. This report summarizes the analyses and findings associated with these four problems.
