Abstract
The product which has fatigue induced failure mechanism always suffers complex fatigue loads accompanied by random shock loads. The existence of shocks can increase the risk of failure because it can not only cause shock damages or shock failure, but also impact the fatigue process. This chapter discussed the dependent relationship between fatigue and shock processes when high cycle fatigue and low-energy shocks are involved. The uncertainty of external loads and internal properties are considered. The reliability of fatigue process is developed with the stochastic fatigue loads and corresponding stochastic fatigue life model based on the impact of shocks. The reliability of fatigue process is also modelled with the assumption of HPP and the effect of fatigue damages. Overall competitive reliability model is proposed with an engineering case of actuator cylinder.
