Abstrakt: Conclusions 1.Further development and experimental substantiation of the principles of the superposition of static and cyclic effects has been achieved as applies to cyclic-creep conditions under a multifactor loading. A function describing the influence exerted by static-load factors on the characteristics of cyclic creep is introduced as a result; to derive a specific form for this function, it is proposed to use methods of optimal planning of multifactorial experiments.2.The equivalent stress of a cyclic multifactor loading, the magnitude of which was found to be invariant with respect to the cyclic-creep and longevity characteristics, is introduced.
