Fracture Mechanics

The objective of this course is to provide students with an introduction to the mechanics of fracture of brittle and ductile materials. Lectures will focus on the basics of linear-elastic fracture mechanics (LEFM) and elastic-plastic fracture mechanics (EPFM) including the J-Integral. Time dependent fracture including creep and fatigue crack growth will be covered. Methods to experimental determine fracture properties (ASTM standards) will be introduced.
