The dual boundary element method applied to semi-infinite surface cracks in two-dimensions
The goal of his thesis is to evaluate the stress intensity factors (SIF) for surface cracks in semi-infinite solids via the DBEM. We first detail the derivations of the boundary element and dual boundary element methods. The main difficulty with these methods are integrations of the singular …

Analysis of the interaction of two parallel surface cracks
… cracks may form in aging aircraft that forms at stress concentrations such as fastener holes and notched components by stress corrosion and fatigue cracking. The lifetime of the structures are significantly affected by the interaction between these cracks. Depending on relative positions and …

The Solution of Hypersingular Integral Equations With Applications in Acoustics and Fracture Mechanics
… We focus our studies on problems addressing the Stress Intensity Factors (SIF) of a finite Griffith crack scattering an out of plane shear wave. In addition, we consider the problem of determining the SIF of two parallel Griffith cracks and two perpendicular Griffith cracks. It is shown that the …

A comparative study of stress intensity factor extraction techniques for the generalized finite element method
… to the user in a choice of an appropriate mesh. Stress intensity factor is an important quantity in fracture mechanics which is used to predict the stress state around a crack front. This report presents a comprehensive study of stress intensity factor extraction techniques: The Contour Integral …
