Photoelastic Analysis of Dynamic Fracture Behavior

  • James W. Dally
Conference paper


Since Tuzi (1928) initiated research in dynamic photoelasticity, the scientific community has witnessed a continuous development of this experimental method and an ever increasing range of application to major engineering problems. Dynamic fracture is one of the more contemporary engineering applications of photoelasticity. The development of this technical area has been delayed since Tuzi first showed that photoelasticity was an effective method for studying dynamic problems, for several reasons. Firstly, fracture mechanics did not evolve as a descipline with a suitable theoretical base until the 1950’s. Secondly, the high-speed equipment, both electronic and photographic, necessary to conduct meaningful experiments was not available until the mid 1960’s. Finally, the interest in the problem was deferred until the phenomena of crack initiation was well understood and engineers became concerned with structural integrity after crack initiation.
