fracture mechanics

This set of homework is on mixed mode fracture and interfacial fracture

Buckling delamination, with two slides on 1D vonKarman plates.

• Z. Suo and J. W. Hutchinson, "Interface crack between two elastic layers," Int. J. Fracture, 43, 1-18 (1990).
• Section III in J.W.

• Williams singularity
• Energy release rate
• Mode angle
• Stress oscillation
• Small scale contact
• Example 1:  A small crack on the interface
• Example 2:  Thin film debonding
• Interfacial fracture energy
• Four-point bend specimen
• Double-cantilever beam
• The use of the interfacial fracture energy

Problem Set 2

I am working on my PhD in Biomedical Engineering at the University of Neb. and have enrolled inES 242r because failure modes of many orthopedic implants can be attributed to initial flaws & fractures of material coatings.  This course, albeit, focuses on ductile materials, the principles seem relevant.

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.

I am pretty new to having a class that is fully powerpoint presentations and am wondering how everyone else is coping with it. Does anyone have any pointers or useful ways they keep notes in powerpoint classes? Printing the notes before hand? Anotating directly on the notes? Having a seperate notebook for notes and seperate handouts of presentation, etc etc?

I am a PhD student at the University of Nebraska Lincoln. I obtained MS in Engineering Mechanics from the University of Nebraska Lincoln, where my thesis was focused on numerical simulation of elastic wave propagation in polycrystalline material, and Bachelor of Engineering in Mechanical from Pune University, India. At present I am working with Dr. Joseph A. Turner in the Ultrasonics and Vibration group. My research is primarily focused on the ultrasonic wave propagation in heterogeneous media using statistical approaches. My research has both theoretical/numerical and experimental aspects for materials characterization and nondestructive testing purposes.
