Analysis of Dynamic Mixed-Mode Crack Tip Stress Patterns.

Abstract

The mixed-mode, elasto-dynamic state of stresses in the neighborhood of a rapidly running crack tip has been used to develop a relation between the isochromatic fringe order and its position parameters. The maximum shear stress is expressed in terms of the stress intensity factors and other higher order terms involving the mixed-mode loading for a crack propagating at constant velocity. A graphics package based on these derivation was developed for mapping the isochromatics in the vicinity of a running crack tip and was used to illustrate typical mixed-mode isochromatics.
