CE597-188: Nonlinear Fracture Mechanics  

(Fall 2021)



Description: This is a graduate course in Fracture Mechanics for those students who are interested in learning more about the concepts of material inelastic 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 elastic fracture mechanics before we look at nonlinear and complex behavior. The final part of the course will be based on  projects where the student will be able to solve some open-ended problems using computational, analytical or experimental tools.
