Abstract
In this note we announce the results obtained in [4] on local and global regularity for quasistatic initial-boundary value problems from viscoplasticity. The problems considered belong to a general class with monotone constitutive equations modelling inelastic materials showing kinematic hardening. A standard example is the Melan-Prager model. In [4] it is proved that the strain/stress/internal variable fields have H 1+1/3−δ/H 1/3−δ/H 1/3−δ regularity up to the boundary. We also show that in the case of generalized standard materials the same regularity can be obtained under weaker assumptions on the given data.
