【 摘 要 】

The present work deals with the experimental investigation involving Quasi-static perforation of thin circular polycarbonate plate for ballistic performance evaluation. Effective diameter and thickness of polycarbonate plate is 205 mm and 2.66 mm respectively. Quasi-static perforation is performed on Servo-mechanical universal testing machine of capacity 50 kN using Blunt and Truncated cone penetrators of diameter 12.8 mm made of EN31 alloy steel. The velocity of the penetrator (indenter) is set at 2 mm/min and the impact is carried out at the centre of the plate. The results obtained based on Quasi-static tests are used in conjunction with the impact test performed using pneumatic gun set-up [1] for the same set of target plate and projectile nose shape. The ratio of the dynamic and quasi-static perforation energy defined as dynamic enhancement factor has been calculated. The variation of dynamic enhancement factor (DEF) with the impact velocity exhibit a linearly increasing pattern similar to those in literature for metallic plates [2].
