Development of Approaches to the Creep Process Modeling under Large Deformations

Abstract

We propose a mathematical model of large elastoplastic deformations with rheological features. As an example of applying the model relations, we present a solution of the boundary-value problem on collapsing process of microdefect continuity in elastic-creep-plastic materials under uniform pressure. In the case of a single micropore we obtained quantitative estimates of this process. The fields of stress and the residual deformation are computed.
