Abstract: In the article the results of finite element calculations for the determination of stress-strain state of elasto-plastic plate with central circular hole which is under the action of cycle loading are presented. Incremental and direct methods of defining asymptotic behaviour of the structure: adaptability, alternating plasticility and progressive plastic flow are presented. In the package Simulia Abaqus incremental cyclic loading of samples with stress concentrators is performed.

Keywords: shakedown, reversed plasticity, ratcheting, finite element method, incremental analysis.
