Determination of histories of SIF distributions for axial semi-elliptical surface cracks in hollow cylinders subjected to thermal shock

The basic equations for a 3D thermal weight function method for Mode I are derived. A novel technique, referred to as the multiple virtual crack extension (MVCE) technique, is proposed for solving the basic equations. Specially selected linearly independent VCE modes can be used directly as shape fu...
