Dear Students of ES 242r / ENGM 940:

You may be interested in reading about the self-introductions of your fellow students. 

The attached notes are written mainly for myself. Most figures are missing. I'll draw these figures in class. So please take good notes in class.

• A stationary, planar crack subject to mixed mode loading
• Values of stress intensity factors
• Mode mix and amplitude of the load
• Crack kinking
• A moving crack selects a mode I path
• Mud cracks in a thin film bonded to a substrate
