Course announcement: "Fracture Mechanics & Complexity Sciences"
Enclosed please find the announcement of a Short Course on FRACTURE MECHANICS & COMPLEXITY SCIENCES taught by Alberto Carpinteri at the University of Pisa (Italy) on April 11-13, 2007.
fracture mechanics
On the crack growth resistance of shape memory alloys
With the increasing use of shape memory alloys in recent years, it is important to investigate the effect of cracks. Theoretically, the stress field near the crack tip is unbounded. Hence, a stress-induced transformation occurs, and the martensite phase is expected to appear in the neighborhood of the crack tip, from the very first loading step. In that case, the crack tip region is not governed by the far field stress, but rather by the crack tip stress field. This behavior implies transformation toughening or softening.

ES 242r personal agenda
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.
Lecture 8 Mixed mode fracture
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.
Class Lectures with PowerPoint
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?
