Examining the Effects on a Fatigue Life of Preloaded Bolts in Flange Joints: An Overview
MetalsThe amplitude of a bolt load in dynamically loaded bolted flange joints depends on several factors: the resilience of the bolt and the clamping parts, the magnitude of the working load, the point of action of the working load, the way the working load is
