Numerical Simulation of Crack propagation Influenced by Thermal and Porous Liquid Stresses
Source abstract
Abstract
A method is developed for tracing crack propagation in a blocky medium subjected to thermoelastic and poroelastic stresses arising due to the porous pressure of liquid or gas. It is based on extension of the CV-BEM methodology to include body forces. The model considers tensile, shear and mixed mode propagation, as well as crack coalescence. Examples illustrate the accuracy and efficiency of the method.
