Strength calculation of parts based on stress state stiffness

Abstract

In the framework of this research it is shown that strength calculation of the most critical parts requires taking into account the parameter of stress state stiffness determined by the G. A. Smirnov-Alyaev. A method for estimating the level of strain of parts and diagnosing the most critical zones of parts based on dimensionless energy and complex criteria is proposed. The effectiveness of the method that can be used not only to diagnose critical zones, but also to optimize the geometric parameters of the design of critical parts, is shown.
