Resumo: | Abstract The present study is based on experimental investigation and numerical simulation of impact of different nose shape projectiles on thin polycarbonate plates. Rigid hardened projectiles of two different geometries (Blunt and Truncated cone) keeping the same shank diameter and total mass were prepared. These projectiles were impacted through pneumatic gun setup on circular polycarbonate plates at varying impact velocities upto 106 m/s. Impact and residual velocities were measured before and after perforation, respectively. Numerical simulations were performed in ABAQUS/EXPLICIT finite element code. The problem has been modelled based on Mie-Gruneisen equation of state. The experimental results obtained in terms of ballistic limit, residual velocity, energy absorbed and deformation mechanism have been compared with the numerical results and are found to be in excellent agreement. It is observed that the ballistic limit for normal impact is greater for blunt projectile compared to truncated conical projectile. Velocity drop and the energy absorbed is higher for blunt projectile compared to truncated conical projectiles for the impact velocities under study. |
