Ballistic Performance Of Multilayered Plates Subjected To Impact By Rigid Projectiles By Finite Element Investigation
Penetration of projectile into steel target is of high interest. The penetration process is highly complex and
due to it interdisciplinary nature, most of the works in this respect are experimental. High cost of experimentation has
forced many of the investigators to rely on finite element investigation of the models. Recent investigations rely heavily
on simulation processes using available software tools.
In aim of this paper is to study the projectile impact response on the multilayer plates. Projectiles with three different
configurations such as blunt-, conical-, and hemispherical- nose shapes are considered. The results of ABAQUS
simulation are compared with the experimental results of valid sources and a very good agreement in recorded.
Also other parameters in the penetration problem such as residual velocity of the projectile, shape of the residual
velocity curve and energy absorption are studied. Finally by observing the results of the above parameters, work concludes
the advantages of the double layer configuration over the monolithic configuration.
