Date/Pages: August 2014; 52 pages
Abstract: This report discusses the implementation of a mechanochemical model for brittle fracture in the government code SIERRA. It is largely based on damage models for which damage is an internal state variable. The model is introduced first in a linear elastic context and then a similar model is developed using finite deformation theory. The model is then verified and some example applications discussed.
