Paper Abstract

Impact experiments have been performed to investigate the fracture phenomena in two different transparent targets: glass and PMMA. Early states after intense impulsive loading were observed by means of IMACON high speed camera and manganine pressure gage. The wave propagation and crack growth into targets were analyzed as a function of time. Microcracks are generated always behind the shock wave front. In glass, the release waves reflected from the free surfaces of target sides may cause to generate secondary cracks in front of the main fracture surface. The wave interaction due to different impedance on the target boundaries affects wave propagation and crack growth.
