Wedge flows of a plasticoviscous medium with nonlinear velocity

The properties of plasticoviscous media have been the subject of numerous studies, in particular [1–5]. This paper deals with the problem of plasticoviscous flow in the absence of a pressure drop of a medium with nonlinear viscosity in pure shear in a region wedge-shaped in plan, and with the problem of flow under the influence of a pressure drop, when one face of the wedge moves parallel to the edge.
