Abstract In this paper, the Discrete Element Method (DEM) is employed to numerically explore the response of hollow cylinder specimens of granular soils under complex stress paths. Two series of numerical tests are conducted to clarify the effects of the principal stress direction α and the intermediate principal stress through the b-value on the ...

Effect of intermediate principal stress on strength of soft rock under complex stress states
Journal of Central South University, 2014A series of numerical simulations of conventional and true triaxial tests for soft rock materials using the three-dimensional finite difference code FLAC3D were presented. A hexahedral element and a strain hardening/softening constitutive model based on the unified strength theory (UST) were used to simulate both the consolidated-undrained (CU ...

It is usually known that the intermediate principal stress and the stress histories have large influences on the deformation and the strength of soil. The influences of these factors, i.e. stress-induced anisotropy, therefore should be considered properly in a constitutive model of soils.

This study examines the macro- and micro-mechanical behaviors of granular materials at a low mean stress in general triaxial loading using the discrete element method. Spheres were used to model the particles to reduce the computational costs. They were placed in the grid points of a cube with their random values of diameters.
