Cohesion yield strain

WebThe post-yield stress state of rock salt is assumed to satisfy the Mohr–Coulomb strength criterion, and a dilation angle can be used to describe the volumetric deformation. The post-yield mobilized cohesion, internal friction angle, and dilation angle were obtained based on the complete stress–strain curves under different confining pressures. WebSep 2, 2024 · This is called the “true” or “logarithmic” strain. During yield and the plastic-flow regime following yield, the material flows with negligible change in volume; …
