Antisymmetrical 3-D stress field near the crack front of a thin elastic plate

Based on detailed three-dimensional finite clement analysis, the near-tip field of a thin elastic plate remotely subjected to Mode II antisymmctrical loading is investigated. The computed results show the transition to a three-dimensional state to occur near the radial distance from the crack tip of 1.5 times the plate thickness. In the close vicinity of the crack front, the asymptotic stress field is characterized by a combination of plane...
