Axisymmetric Compression of a Mohr-Coulomb Medium with Arbitrary Dilatancy, Including Free-Field Yielding

Abstract

A dosed-form analytical solution is developed for hole closure and stresses and strains in a Mohr-Coulomb medium surrounding a circular hole and loaded axisymmetrically in plane strain. This solution extends multiple-plastic-zone solutions developed by others to allow arbitrary dilatancy. It also extends the solution to include cases where particular combinations of friction angle, elastic properties, and free-field pressure cause the free field to yield before significant deformation of the opening occurs. Step-by-step procedures for applying the solution and numerical examples are presented.
