| Abstract |
The problem of deformation of an elastic-viscoplastic material in the gap between the coaxial cylindrical surfaces of a rotary viscometer is considered. The loading of the material occurs due to a slow rotation of the outer wall of the viscometer; at this stage, the condition of adhesion of the material to the walls is assumed. At a certain critical angle of rotation, material slip occurs, which causes the unloading shock wave to propagate in the layer. When the wave propagates, it interacts with the elastic-plastic boundary and is reflected from the walls of the viscometer. The unloading dynamics is investigated using the ray method for constructing near-front expansions. |
