Abstract
The mathematical model of sequential growth of irreversible deformations in materials having elastic, viscous, and plastic properties is proposed. The model is illustrated by the solution of the problem on the occurrence of visco-plastic flow, its development, and deceleration in a material located between rigid cylindrical surfaces.
