Abstract
The total deformation is decomposed into its plastic and its elastic part. This means the final configuration of the plastic deformation is the stress-free reference configuration for the elastic deformation. However the intermediate state is not a continously differentiable vector field and the plastic and elastic deformation tensors are not gradients. Their incompatibilities are determined. The plastic work and the flow rule are considered. Finally the equations for the unloading process are given.
