Abstract

In this study, the fragmentation occurring with ballistic impact was researched with finite element method by using Ansys Autodyn software, and using different modelling methods, the most accurate and precise method was selected for the problem. After determining the method, the finite element model was generated and solved for two different types of ballistic armor (Al5083 & RHA). Spall distribution was observed and close results obtained between finite element and experimental study. Having good agreement between experimental and numerical study the research continued with spall liner (Kevlar/epoxy) addition after armor plate to reduce spall distribution.
