โœฆ Synopsis

A B S T R A C T An elastic-plastic analysis is performed for an infinite plate under plane stress conditions which contains a finite line crack and is subjected to biaxial loading. In the large scale yielding range, the amplitude of the dominant singularity at the crack tip, the plastic stress (or strain) intensity factor, is found to depend on the magnitude of loading parallel to the crack direction. The predicted value for the fracture initiation stress which is based on a plastic intensity factor fracture criterion, increases under lateral, tensile loading. Compressive loading parallel to the crack has the opposite effect on the fracture initiation stress.

In developing the fracture mechanics to assess the structural integrity of a cracked trunnion in a ball mill [1], we discovered that the standard compendia ([2]-[4]) of stress intensity factors did not contain the one we needed, that for a bent thin cylinder with a circumferential crack. As a result
