Themain goal of this work is to study the ballistic performance ofmulti-layered moderately-thick metallic *** target configurations have been considered in thiswork,with various types of interlayer connection(spaced,contacted and adhesive)and the number of layers(four and eight),and the influence of target configurations on ballistic performance has been studied experimentally and *** the experiments,the targets were impacted by 12.7-mm projectiles at a velocity around 820 m/*** experimental results show that,with similar total thickness,the contacted and adhesive targets exhibit better ballistic performance than the monolithic targets,and the four-layered targets are better than the eight-layered targets with the same connection *** explore the ballistic resistance mechanism,numerical method has been used to simulate the penetration process of each *** numerical results indicate that petal formation and friction have significant influence on targets’ballistic *** has stronger influence on themulti-layered targets than on themonolithic *** to the numerical results,about 14%of projectile’s initial kinetic energy is dissipated by friction during penetrating the four-layered contacted target,which is proved to be the most effective type of target studied in *** results also indicate that,in contrast to common understanding,friction plays an important role even when the impact velocity is significantly higher than the ballistic *** outcome of this work may provide useful information for a better understanding of ballistic resistant mechanisms and more efficient utilization of multi-layered metallic targets in armor structural design.
