EGM 6570 PRINCIPLES OF FRACTURE MECHANICS

Spring 2013

Catalog Description: An introduction to the mechanics of fracture; Emphasis on modeling and prediction of crack initiation and growth in engineering materials; Topics include: linear elastic fracture mechanics, elastic-plastic fracture, fracture testing, numerical methods, creep and fatigue fracture.

Goals: To be able to predict failure of engineering materials near cracks

Engineering Applications: Relevant to all areas of structural/mechanical design. Especially important for high-performance materials such as in aerospace applications, but important from bridges to machine components to electronic packaging.
