UDEC - A Generalised Distinct Element Program for Modelling Jointed Rock.

Abstract

A NEW COMPUTER PROGRAM, UDEC, has been developed which simulates the behavior of jointed rock masses subjected to high and transient loadings. It is an explicit, time-marching procedure that models assemblages of discrete blocks or particles that interact mechanically. The program includes modes that describe the behavior of rigid blocks, simple deformability, and full deformability. The modes and other components are also designed to interact so as to model other kinds of physical behavior, such as fluid interaction, edge-to-edge contact, and soft corners. (Author)
