Engineering Physics Annotation << Back DETERMINATION OF NONLINEAR PARAMETERS OF ELASTIC PROPERTIES OF ROCKS IN THE STUDY OF GEOMECHANICAL PROCESSES N.G. VYSOTIN, YU.P. GALCHENKO, V.A. VINNIKOV, V.A. EREMENKO There is justified the determination of nonlinear parameters of the elastic properties of rock samples for further modeling of geomechanical processes. There are presented theoretical models of determining the parameters of the hysteresis nonlinearity of the elastic properties of rocks. There are presented a method for determining the coefficients of a nonlinear equation describing the behavior of a marble sample under elastic hysteresis. Keywords: structurally heterogeneous materials, elastic hysteresis, stress-strain state, convergent mining technologies, mining systems, rocks, physical modeling.
