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.
