Plasticity and Creep of Materials at Variable Stresses

Abstract

The article deals with the modeling of elastic-plastic behavior and creep of aluminum alloys. On the basis of the treatment of equilibrium stretching diagrams and creep curves, nonlinear dependences describing the phenomena under consideration are constructed. A feature of the paper is the consideration of the creep process under varying stresses, when the growth of deformations in time is accompanied by stress relaxation.
