In the present work the bond strength of two friction welded polymers was investigated when the bi-material specimens were subjected to projectile impact at 86 ms-1. Two transparent polymer rods of Polycarbonate(PC) and Polymethylmethacrylate Acrylic(PMMA) were joined together using rotary friction welding. Specimens were cut into two different bat

In the present research work a 100 mm long copper pipe segment with a 1 mm wall thickness is subjected to a drop weight impact by a conical shaped steel indenter with varying nose angles but constant mass. The impact velocity of the indenter was kept constant so that the kinetic energy available at impact was same for all cases. The effect of inden
