Shear stresses in shrink fit assembly? I'm trying to figure out what shear stresses there would be from a shrink fit assembly, if any. You have a cylindrical solid shaft and a cylindrical hub, where the shaft diameter is greater than the hub's hole diameter. The shaft cooled and thus shrunk and the hub is heated and expanded so they will fit together, then allowed to come back to the original temperature. Will either the shaft or cylindrical hub experience any shear stresses?
