Fatigue strength and life of real structures under combined random loading

Abstract eng:
A rather often kind of combined stress is a case, when one of its components acts statically. The contribution deals with some results of research works, the goal of which has been to reveal an influence of the static component on a resulting fatigue life, and to find a way of its including into fatigue strength evaluations. A procedure for finding a critical stress for an estimating of a structure save life is presented. Unfortunately, the fatigue life calculation is more complicated and needs some experiments, whichj will yield additional information on a material behaviour under required stress combination and levels.
