Energy-based fracture evolution

Applied and Computational Mathematics Seminar
Monday, October 25, 2010 - 1:00pm
1 hour (actually 50 minutes)
Skiles 002 (Ground floor, entrance from Skiles courtyard)
I will describe a sequence of models for predicting crack paths in brittlematerials, with each model based on some type of variational principleconcerning the energy.   These models will cover the natural range ofstatics, quasi-statics, and dynamics.  Some existence results will bedescribed, but the emphasis will be on deficiencies of the models and openquestions.
