We consider problems of elastic plastic deformation with isotropic and kinematic hardening.
A dual formulation with stresses as principal variables is used.
We obtain several results on Sobolev space regularity of the stresses
and strains.
In particular, we obtain the existence of a full derivative of the
stress tensor up to the boundary of the basic domain.
Finally, we present an outlook for obtaining further regularity
results in connection with general nonlinear evolution problems.
