Peculiarities in the formulation of boundary value problems of deformation mechanisms, when at the boundaries of the fields of plastic or viscoplastic flows, there are simultaneous changes in the mechanisms of production of irreversible deformations are discussed. This is inevitable, unless irreversible creep deformations are neglected. With the development of plastic flow field, this mechanism changes from viscous (creep) to plastic (flow).
