Mathematics and Statistics Faculty Publications and Presentations

The evolution of a distribution of material inhomogeneities (defects, dislo-cations, etc.) is investigated. Adopting our recently developed model of the anelastic evolution law of a defective solid crystal body and using the classical methods of the theory of hyperbolic waves we analyze such phenomena as the long-term relaxation of defects and the dislocation pile-up.
