A DEM code was developed, and used to simulate the response of the continuum materials to loading.
Introduction Rock materials exist in the fissured state.
Under external loads, fissures or cracks will nucleate and propagate, and finally cause the rock materials to fail.
The program developed was used to simulate the response to loading of continuum materials.

Fig.1 Section form Unified Strength Theory The unified strength theory was established by YU [6] based on the twin shear strength theory, which considered the effects of intermediate principal stress and can be applied to a variety of different materials.
The restraint stress decreases with the increase of material parameter , while the restraint stress increases with the increase of material parameter .
