Abstract

Circular-fronted cracks in round bars subject to tension, bending and twisting are considered. Numerical expressions are given allowing the calculation of stress intensity factors KI, KII, KIII at every point on the crack front for a wide range of crack geometries. Comparisons are made with analytical, experimental and numerical results abailable in the literature. Crack shapes satisfying the iso-KI criterion are also determined, making it possible to investigate the problem of crack growth behaviour under tensile or bending fatigue loads.
