Tensile failure criterion for transversely isotropic rocks

A common problem encountered in rock engineering involves the specification of strength anisotropy in transversely isotropic rocks such as slate and schist. The strength anisotropy under compression has been relatively well established, whereas the formulation of the tensile strength anisotropy has received less attention due to the difficulty of experimental validation. In this paper, a recently developed 3-D tensile failure function for …
