Dynamic photoelastic studies of fracture

Dynamic photoelasticity is applied to characterize the behavior of cracks propagating in polymers and a metal with an⇘-K relation
  • James W. Dally
The William M. Murray lecture, 1979


Dynamic characterization of brittle fracture is possible by relating the instantaneous stress-intensity factorK(t) to the velocity of propagation of the crack. High-speed photographic systems are employed with photoelastic methods to obtain a sequence of isochromatic-fringe patterns representing the state of stress associated with the propagating crack. Methods for determiningK(t) from these isochromatic patterns are reviewed.
