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

โฆ Synopsis
The stress intensity factor solution given by Isida et al. for semi-elliptical surface cracks in plates is improved and extended. The data tabulated for the ranges 0 ~< a/t <~ 0.6 and 0.25 ~< a/c ~< 1.0 were checked using the energy relation and found to be superior to solutions available in the literature.

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)
This paper analyzes the interactions of two coplanar semi-elliptical surface cracks located, respectively, at the front and back surfaces in a finite thickness plate under uniform tension. Few numerical solutions app,~ar to be available in the literature so far for this kind of interaction. The anal
