A Basis for Modelling Ceramic Composite Armour Defeat

Abstract

This work takes some of the major features of ceramic composite armour failure, viz. fracture conoid formation, dishing failure of thin backing plates, perforation failure of thick backing plates, and projectile erosion, and by lumping masses to treat material acceleration simple models are developed which allow computations on ceramic targets with both thin and thick metallic backings. Two computer programs for these problems, CEP and ECS, are documented, and calculations compared with a broad range of empirical data and also used to discuss aspects of the interaction of penetrators with ceramic composite armours. The good correlation of models with experiment demonstrates the usefulness of the present approach for studying ceramic composite armour defeat.
