Description
Summary:— Calculations are given of the distribution of strains, stresses, and temperature during the deformation of an elastoviscoplastic material clamped between coaxial cylindrical surfaces and initially retained by dry friction against the boundary surfaces. Due to the given variable advancement of the outer of them, the material slips and its viscoplastic flow begins (not simultaneously). The process of flow development with its subsequent deceleration to a stop, material unloading and cooling to room temperature is considered. Heat is produced by sliding friction against a rough boundary surface and by irreversible deformation (a related problem of large deformation theory). A deformable material is considered to be mechanically incompressible, when the change in its volume is associated only with thermal expansion, the yield strength is assumed to depend on temperature.
