This research will analyze mathematical models for certain                 polymers and ductile materials in order to predict the failure of               such materials under external forces.  The models to be used are                nonlinear elasticity and viscoelasticity.  Mathematically, the                  problems involve the existence of singular solutions to                         quasilinear elliptic and hyperbolic systems, and the existence of               minimizers with singularities for problems in the calculus of                   variations.                                                                          This work has applications to material failures associated                 with the formation of cavities in the material and failures due                 to wrinkling of the material surface.
