| Abstract |
Mechanical models of rocks subjected to various bulk stress states are considered. The models contain the Nadai parameter, which takes into account various types of the bulk stress state, the potential energy of bulk variation, and the potential energy of variations in the shape of rock elements in the equilibrium stress-strain state. These variables permit determining the conditions under which rock massifs stay in equilibrium and the conditions under which rock can cease to be in equilibrium owing to the bulk stress state action; they also allow one to justify the physical parameters of the rock strength certificate under the bulk stress state action and determine the constraint equation relating the stress and strain invariants for inhomogeneous rocks. |
