Abstract

This paper describes the first experimental observations of various phenomena characteristic of dynamic intersonic decohesion of bimaterial interfaces. Two separate but complementary optical methods are used in conjunction with high speed photography to explore the nature of the large scale contact and mach wave formation at the vicinity of running cracks in two different bimaterial systems. Theoretical predictions of crack‐tip speed regimes where large scale contact is implied are confirmed. Also, the theoretically predicted mach wave emanating from the intersonically propagating crack‐tip is observed. Direct visual evidence is also obtained for another travelling mach wave emanating from the end of the intersonically moving contact zone.
