An upper bound analysis for the plugging type of ballistic perforation on the double and multi-layered armour plates

복층 및 다층장갑판재의 관통에 대한 상부경계이론 해석

A modified theoretical analysis of the ballistic perforation on the double and multi-layered armour plates using an upper bound method has been presented in this paper. A modified model based on the suggestion of the Awerbuch-bodner model has been adapted and extended into double and multi-layered armour plates when the plugging type of penetration has been occurred. The residual projectile speed, ballistic limit velocity and contact time during the penetration process have been derived from the equation of motion at each stage.
