Abstract
The impact behaviour of polyethylene plate has been experimentally and numerically investigated. The analysis involves determination of the ballistic impact behaviour of polyethylene plates under dynamic impact of rigid conical nose shape projectile. The experimental investigation has been carried out using pneumatic gun set-up with arrangements for recording the impact velocity and residual velocity after perforation. The experimental investigations, are supplemented with the numerical analysis based on FE code using ABAQUS/EXPLICIT. Mie-Gruneisen equation of state is employed for modelling of the problem. A detailed analysis has been presented to explore the mode of deformation, ballistic limit and the failure characteristics of the polyethylene plate under normal impact of conical projectiles.
