Begun, A.S., Kovtanyuk, L.V., Lemza, A.O. On modelling of creep and plasticity in a problem of viscosimetric flow of a material // Key Engineering Materials. 2016. V. 685. Pp. 230 – 234.

This paper considers a deformation process of an incompressible elastoviscoplastic material placed between two coaxial rigid cylinders. The material is deformed when the internal cylinder rotates around its axis while the external one is fixed. The adhesion conditions are set on both boundary surfaces. The theory of large elastoviscoplastic deformations is used to solve the problem. The mathematical model is constructed in cylindrical coordinates.
