Paper Abstract

In this paper, dynamic caustic method is applied to analyse the crack propagating problem of a plexiglass double cantilever beam (DCB) specimen. The varying curve of dynamic stress intensity factor (DSIF) with crack propagating velocity (v) has been drawn. The results show that this method will find a wide use in those transparent materials which has no optical double-refracted character for dynamic fracture mechanics research.
