In this Chapter we begin to study the statistical effects in failure analysis of springs. It presents the procedure for dimensional analysis of failures of the helical springs. The dimensional analysis spring element is examined with the weakest-link concept. This concept is applicable to the extremely brittle material, for which the failure of one link causes the complete destruction of the complete structural element. The variation of stress over the surface of the wire is accounted for the analytical calculation of Weibull failure probability. Chapter delivers analytical formulas for failure probability of helical springs. The derived solution clarifies the effects of spring index and wire diameter on the fatigue life. The methodology is valid for different types of springs or basic structural elements.
