Development of Generalized 2-D and 3-D Distinct Element Programs for Modeling Jointed Rock

Abstract

The capabilities of the UDEC computer program have been improved to provide full generality of the program for modeling jointed rock. Complete features exist for simulating variable rock deformability, nonlinear behavior of distinct joints and intact rock, dynamic cracking, projectile impaction, and fluid flow and fluid pressure generation in joints and voids. Further, the first stage in the development of a three-dimensional distinct element code has been completed. A new data structure has been designed and a test-bed code produced for three-dimensional analysis. Additional keywords: Computations; Rock mechanics; UDEC(Universal Distinct Element Code); Mathematical models.
