The student, upon successful completion of this course, will be able to:
1. Correctly apply fracture mechanics (KIc, Gc, JIc) to predict material frailure.
2. Identify and describe the basic fracture and fatigue mechanisms.
3. Correctly predict fatigue life using S/N and fracture mechanics based methods.
4. Correctly identify the cause of failure of a material based on fracture surface observations.
