Разработка критериев анализа напряжённо-деформированного состояния деталей ГТД в упругопластической области

Abstract

The presents the dimensionless criterion complex that is based on the ratio of stress state stiffness and energy criterion characterizing of the material tension in the elastoplastic region to use it for analysis of the stress-strain state with the purpose to diagnose the most vulnerable for damage regions of gas turbine engine parts. The efficiency of criterion is shown by the example of gas turbine disks improvement.
