CE597-085: Nonlinear Fracture Mechanics  

(Spring 2013)



Description: This is a graduate course in Fracture Mechanics for those students who are interested in learning more about the concepts of material deformation and failure in the context of solid mechanics when cracks are present. The class will be introductory in nature as we will start with the fundamental concepts of solid mechanics and linear elastic fracture mechanics before we look at nonlinear behavior. The student is assumed to have taken at least a class on solid mechanics, continuum mechanics, elasticity, etc. .
