    Shear Fatigue in bolted Connection

    Yes it has a clearance hole and I think you are referring to alignment pins and dowels that are usually in pure shear but I know our maintenance department and I fear they will not tighten the bolts with the proper pre load to prevent the bolts from seeing a cyclical shear load. Do you recommend...

    Shear Fatigue in bolted Connection

    I am wondring if there is an endurance limit to adjust the ultimate tensile strength of bolts in fatigue shear loading. I am using Se=.5*Sut for Sut<200ksi developed from the Rotaing-Beam test for tensile fatigue loading. I am designing a frame that will hold a disc brake system to stop a...
