This framework incorporates a micromechanical approach of continuous damage modeling, where damage in a homogenized representative microstructure is introduced at the continuum scale through the material constitutive matrix. In this research, damage in the representative microstructure is simulated utilizing cohesive zone models (CZM) whose properties are a function of the magnitude of applied stresses and the resulting separation. In order to minimize the mesh dependence of the cohesive zone model an adaptive meshing technique is employed. A fatigue simulation is performed to demonstrate the capability of the framework to predict the initiation and evolution of damage. 2011-06-24 English text Wright State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=wright1308257790 http://rave.ohiolink.edu/etdc/view?acc_num=wright1308257790 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
