✦ Synopsis

The lattice statics method for simulating a brittle crack will be employed to answer the following questions:

(1) What is the energy-based criterion for crack stability, (2) At a given stress intensity in the stable region, what is the kinetic barrier for crack motion, and (3) What assumptions break down in the Griflhh theory when generalized to a lattice model. A simple model is used in the analysis, but this model is general enough to provide a conceptual framework for more realistic models.
