The influence of the mutual relationship between dilatancy and fluid flow on the strength of localized shear bands in permeable rocks

The paper is devoted to the numerical study of the influence of the mutual relationship between dilatancy of solid skeleton and pore fluid inflow on the value of shear strength of shear bands in rocks. We show that this influence has a nonlinear and nonmonotonic character and strongly depends on the degree of confinement of a shear band. The results of the study broaden the understanding of possible limits of the change in the strength of...
