Violent Elastic-Plastic Wave Motion
This talk will describe some physical phenomena that occur when a solid is subject to a stress that greatly exceeds its yield stress and also discuss a mathematical model for uniaxial wave motion in such a solid. This model leads to some interesting questions concerning degeneracy in hyperbolic pdes and causality of interfaces.
