Finite Element Analysis of Stresses, Deformations and Progressive Failure of Non-Homogeneous Fissured Rock. Volume I. Main Document
The objective of this research program was development of finite element procedures for prediction of stresses and deformations in the vicinity of underground excavation. Two models of rock behavior were selected. In one the rock is treated as isotropic elastic-plastic following a generalized Mohr-Coulomb law and in the other the rock is isotropic elastic-brittle subject to Griffith or modified failure theory. For each model, mathematical relationships governing stress-strain behavior and progressive failure were developed. Finite element computer programs incorporating each of the two models were coded. Preliminary to this development, a revised version of Zienkiewicz's no-tension analysis was programmed. The report contains the theoretical development, and discussion of application of the techniques to theoretical solutions, experimental data, published results and a parametric study of forces in structural supports for a tunnel excavation.
