Abstract

In practice of designing of machine details and the equipment for assessment the hazard of a tense situation usually use not criteria of strength, only the safety margin coefficient or equivalent stress. Methods of calculation of equivalent stress are considered on the basis of a method of calculation of criterion of strength depending on synchronous change of all three principal stresses. Obtained theoretical results are confirmed experimentally and the method of calculation of equivalent stress is developed that is necessary for practice.
