The weight function method is applied to solving three-dimensional linear elastic fracture mechanics (LEFM) problems. Within the framework of the present approach the fundamental equations of LEFM are satisfied and the minimum of additional assumptions are used. The crack opening displacement field

Asymptotic behaviour of weight functions has been analysed for mode I cracks in the shape of an ellipse or part of an ellipse. For internal points of a contour, a well known asymptotic solution is used for a semi-infinite crack with a straight front. An analytical description is suggested for weight
The weight function for the surface point of a semi-elliptical crack in a plate of finite thickness has been derived and tested against numerical data available in the literature. Derivation was accomplished by using the universal weight function form and two reference stress intensity factors. It w
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. The superposition method is used for transfer from th
