This paper describes the results of numerical study to investigate the perforation resistance of sandwich structures. The impact response of plain foam samples and their associated sandwich panels was characterised by determining the energy required to perforate the panels. The dynamic response of the panels was predicted using the finite element analysis package Abaqus/Explicit. The FE model was also used to investigate the effect of oblique loading and to study the impact response of sandwich panels on an aqueous support. The FE analysis accurately predicted the impact load-displacement responses and the perforation energies of both the plain foams and the sandwich panels. The analysis was used to estimate the energy absorbed by the skins and the core during the perforation process.
