A simple method is described which allows the estimation of local stress intensity factors of two-dimensional cracks by use of the weight function basic relation. The method is applied especially to semi-elliptical surface cracks. Two examples are considered. The half-penny shaped crack under bendin
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
Stress intensity factors are calculated at the deepest point and at the surface points of circumferential semielliptical surface cracks in a thermally shocked pipe. The method of calculation is based on weight functions following a proposal by Munz et al. Numerical values of the stress intensity fac
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)
