Effect of the difference of materials of the fastening and abutting members of shearing joint on the distribution of contact pressure

The solution obtained for the distribution of a long contact load with the bolt pressure on the wall of a hole in abutting members of a shearing joint is corrected and extended to the more general case where all members of a joint are made from materials differing in their mechanical characteristics. It is shown that the difference in the elastic modulus of materials of the fastening and abutting members affects the distribution of contact pressure significantly less than the ratio of their diameter and thickness.
