WebBasically, riveting belongs to a forging process that used to join the structures together using a metal part called a rivet. The straight metal pin is connected through the adjacent surfaces. Then both ends are formed over the connection … WebThe additional bending, referred to as secondary bending, will increase notch effects in these joints. Furthermore, fasteners in a simple lap joints are loaded in single shear … Webdistribution are affected by the secondary bending phenomenon. The eccentric load path in single shear lap joints adds the issue of lateral deflection (or secondary bending) of the joint, which generates a non-uniform contact pressure between the fasteners and the hole edge.
