| Goals: |
To provide an in-depth treatment of advanced topics in fracture mechanics including fracture and crack growth under elastic-plastic, time-dependent and dynamic conditions.The course emphasizes the fundamental underpinings of nonlinear fracture mechanics and its use in material evaluation and life prediction methodology for components. Micro-mechanics of fracture and crack growth processes are also covered. Upon completion of the course, the students should be able to read and follow current research papers in fracture mechanics. |
