In this chapter, the effects of mean stress, multiaxial loading, and residual stresses on fatigue life of springs are reviewed. We study the fatigue life of the homogeneously stressed material subjected to the cyclic load with a non-zero mean stress. Traditional methods for the estimation of fatigue life are based on Goodman and Haigh diagrams. The formal analytical descriptions, namely stress-life and strain-life approaches, turn out to be more appropriate for the numerical methods. The reported above method of fatigue analysis, which is describes the crack growths per cycle, is extended. The extensions enable the accounting of the mean stress of load cycle. The closed form expressions for the crack length over the number of cycles are derived. The complement effects on the fatigue life of springs, which eventually significantly influence the fatigue life of springs, are concisely pronounced. This chapter is the second section of the third part, which investigates the lifecycle of the elastic elements.
