Evaluation of T-stress for the case microstructurally short fatigue cracks

Abstract

The paper presents evaluation of the elastic T-stress in the case microstructurally short fatigue cracks, i. e. for cracks for which the crack size is comparable to the scale of the chracteristic microstructural dimension such as the grain size. The microstructurally short crack is modeled as a crack with its tip in the vicinity of an interface between two different elastic materials
