| Abstract: | In this paper, the problem of viscoplastic flow of an incompressible non-Newtonian material between two rigid coaxial cylindrical surfaces in the case of helical motion of each of the cylinders is solved. The deformation under an increasing, constant, and decreasing loading is considered. The problem is solved by using the model of large elastoviscoplastic strains. The parameters of the processes under study are calculated for the domains of reversible strain, for the domains of viscoplastic flow, and for the unloading domains. |
