BLOCK SEAMS MODEL FOR DISCONTINUUM MECHANICS ANALYSIS
Abstract
Based on the characteristics of rock structures, the block seams model, which can be used in the numerical simulation of the continuum and discontinuum mechanics, is established by constraint variational principles. In this model, the continuous condition is introduced into the energy functional by the Lagrange method and penalty method so that either the continuum or discontinuum problems can be simulated by the model. The formulations of the rigid finite element and traditional constant stress element...
