Abstract

A mathematical model has been developed to assess the damage to composite panels subjected to blast loading due to detonation of a conventional warhead in its vicinity. The theory is based on large dynamic deformation incorporating the effects of transverse shear deformation. A damage criterion based on Tsai-Hill/Hoffman failure criterion has been used. The results have been compared with those obtained by classical theory.
