The stress intensity factor at the deepest point of a semi-elliptical surface crack is calculated for stress gradients in direction of depth. The method is based on weight functions. The crack opening displacement for the reference problem is calculated with a method proposed by Petroski and Achenba
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
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
