Taylor impact tests were performed on ductile and brittle materials metals and the results indicate that failure is initiated by the coalescence of lateral release waves behind the incident shock formed upon impact. The failure process in the ductile materials involves nucleation and growth of voids and in the brittle materials it is shear-induced micro-cracking.
