1.To develop a proper mathematical model, in terms of weakly singular boundary integral equations, that governs the data essential and sufficient for computing both the mixed-mode stress intensity factors and the T-stress for cracks in three-dimensional elastic media.
2.To develop an efficient and accurate numerical technique to extract both the stress intensity factors and the T-stress for isolated cracks in both isotropic and generally anisotropic linearly elastic infinite media.
