Triaxial Test Instability of a Nonassociated Flow-Rule Model

The Mohr-Coulomb yield condition with a nonassociated flow rule is often used to model the behavior of dry or drained sand. A previous paper demonstrated, using a single shear band with a rotating orientation, that a genuine but limited instability would occur in such a model at each state of triaxi...
