Influence of dilatance speed on stress-strain state of rocks under explosion of cylindrical charge in air cavity (English)
0 references
Results of numeric solution of the problem about impact of a cylindrical charge of chemical explosive substance in a coaxial air cavity on rock are presented. The one-dimensional mathematical model of transient dynamic process in multiphase medium is based on equations of motion of continuum, isentropic constitutive equation for products of detonation, energy constitutive equation for air and relationships of elastoplastic dilatance model for rock. Influence of speed of dilatance on mechanism of deformation and fracture of rock is studied.
