The present chapter explains the customary ways for accounting of the stress amplitude for fatigue life of springs. The fatigue of spring materials for fully reversed, uniaxial loading is reviewed. Two different estimation methods for fatigue life are briefly discussed. The first method implements the stress-life and strain-life procedures. The second method describes the fatigue crack growths (FCG) per cycle. Two analogous unifications of FCG functions are proposed. The expressions for spring length over the number of cycles are derived. This chapter is the second section of final part, which investigates the lifecycle of the elastic elements.
