Model for Rigid Projectile Perforation of Brittle Targets

摘要

A model to predict rigid, sharp-nosed as well as blunt-nosed projectileperforation of homogeneous target plates has been proposed. The target materials were assumed to be perfectly elastic-plastic so that their deformation can be characterized by the yield strength (Y SUB T). However, the experimental results were obtained for more or less brittle target materials, namely steel armour and dural. Despite this difference, the agreement between the model predictions and the experimental results is satisfactory.
