Abstract

The closed mathematical model of geomaterial with account for internal friction, dilatancy and anisotropy of the material properties is formulated to solve the problem of geomaterial flow in a convergent radial channel in terms of the general conception of rocks as a medium with internal sources and outflows of energy. The developed finite-element algorithm and software enable solution of deformation boundary-value problems in quasistatic formulation. Numerical solutions to the problem of geomaterial flow in a convergent radial channel are obtained. The stress-strain state patterns of the geomaterial medium under different parameters of the problem are presented.
