Sandwich panels for protective barriers

A new high strength, lightweight stainless steel of sandwich construction has been developed for application in automobile and truck bodies. One attractive feature of this material is good resistance to penetration and/or perforation by foreign bodies. The aim of this research is to investigate how penetration and perforation resistance of this type of material are affected by design of the core, the relative thickness of the face plates and the proximity of stiffeners.

Project Details

Penetration and perforation experiments at subordinance impact speeds will be conducted with both rigid and deformable missiles striking sandwich panels at various angles of obliquity. Simultaneously, theoretical analyses of sandwich panel deformation and fracture by low speed missiles will be developed in order to guide optimization of the panel for protection against perforation.
