The problem of a beam containing a semi-elliptical surface crack and subjected to tension or bending loading is investigated. The stress-intensity factor along the crack front can be calculated assuming a model with finite strips arranged in series and parallel. Several cases are analysed varying th

intensity factors were calculated at the deepest point and at the surface points of longitudinal semi-elliptical surface cracks in a thermally shocked pipe. The method of calculation is based on weight functions following a proposal by Mattheck, Munz and Stamm, Engng. Fract. Mech. 18, 633-641 (1983)
Surface. cracks under peak stresses are investigated. The calculational procedure is based on the general form of the weight function for an elliptical crack embedded in an infinite solid. Two points on the contour of the ellipse are investigated. A new correction procedure for transfer from the emb
