Abstract :
The importance of penetration and perforation into targets in both, military and civilian application has made it the subject of many investigations. The current investigation is focused on the ballistic performance of Polymethylmethacrylate (PMMA) under impact by a rigid spherical projectile in the range of 89.3 – 670 m/s. An analytical model for the ballistic limit velocity from the work done for target based on the experimental observations is suggested. The results are discussed in terms of the work done in causing the failure modes coupling this work with the projectiles kinetic energy drop and its effect on the ballistic limit velocity. The effect of target thickness on the velocity is then discussed. The experimental results showed good agreement compared with Ipson and Recht equation
