Such failures can cause partial/complete break-down of the engine and can result in a significant warranty cost. In this work, fretting fatigue evaluation is carried out for a simple geometry of a flat-flat, complete contact pair and a complex geometry of actual head gasket joint. Since the head gasket is a type of flat-flat, complete contact pair, equivalent analogy is assumed between the two problems. A new approach based on deviatoric strain amplitude-based parameter combined with Ding’s parameter, 𝐷𝑓𝑟𝑒𝑡2 is proposed and explored through this work.enFretting FatigueFretting WearHead GasketRuiz ParameterLow Cycle FatigueDeviatoric StrainCritical Plane MethodCrack Initiation MethodProgreaaive WearDing's ParameterCritical DistanceThesis
