The research project is concerned with an initial-                         boundary value problem from nonlinear elasticity theory                         involving nonmonotone stress strain relations.  The                             stable solutions for such a problem will have to minimize                       a noncovex energy functional.  They may exhibit discon-                         tinuous gradients related to changes of phases.  The                            existence of such stable solutions and their long time                          limiting behavior will be investigated.                                              The research results will have practical implications                      in engineering mechanics.
