Approximation of limit amplitude diagram for destructive elements of safety devices

Approximation of limit amplitude diagram for destructive elements of safety devices

The maximum stress of the cycle should be limited not by yield strength but by tensile strength of detail material intended to be destructed. Therefore, such widespread linear approximations of Haigh diagram and conditions of Soderberg and Serensen-Kinasoshvili are not applicable for such details. S...
