Surface cracks or flaws are assumed to be semi-elliptical, and solutions are compared in the matter of SIF values at the center of the crack front and at the external surface of the cylinder, so that a wide range of crack aspect ratios and relative crack depths are studied, in order to provide the engineer with solutions applicable to different real situations in fracture mechanics or damage tolerance analyses such as static or cyclic (fatigue) loading, environmentally assisted cracking or corrosion-fatigue.
