Abstract
A three-dimensional formulation of the distinct element method is embodied in computer program 3DEC, which has been adapted to run on a personal computer. This formulation is based on a dynamic (time domain) solution algorithm which solves the equations of motion of a three-dimensional block system by an explicit finite-difference scheme. The scheme is well suited in rock mechanics studies to determine if a discontinuous rock mass will fail under a given set of applied loads. Part II of this paper describes the mechanical calculations of rigid body motion and block interaction. Part II also presents the technique used in 3DEC to generate a three-dimensional model for rock mechanics analysis. Several examples are provided which demonstrate the capabilities of 3DEC and the size of problem that can be analyzed on a personal computer. The examples emphasize the use of microcomputer graphics to assess model results.
