Abstract
The effect of eccentricity on the stress intensity factors for circumferential cracks in cylindrical specimens subjected to torsional and axial loading is studied. BEM solutions are compared with proposed approximate methods and some agreement is found for the axial load cases. A simple method of how the eccentricity develops under axial loading as the crack grows is presented. It shows that the eccentricity accelerates as the crack grows and that the problem thereby can be characterized as unstable.
