| Abstract: | Crack tip stress and displacement fields are useful for studying the fracture behavior of cracks in both isotropic and anisotropic materials. Under certain boundary conditions, crack surfaces could overlap, a condition that could be more prevalent for the anisotropic case as compared with isotropic materials. Conditions can be derived for different loading conditions and material properties such that overlap of the crack faces would not occur. |
