摘要：
We discuss the methods of assessment of stress-strain state and stress gradient in nonuniformly stressed structural components under elastic and elastic-plastic cyclic deformation. We systematize the research findings on fatigue of metals and alloys, including the stress concentration case, as well as the methods that describe the dependence of fatigue characteristics on the stress gradient.
