Analytical study on slip and yield resistance of bolted friction lap joint

Abstract

The method of calculating slip and yield resistances of the friction type of joints with double frictional surfaces determined on the basis of many results of the tensile tests. However, the slip and yield resistances of the joints with single frictional surface and lap joints have been still unclear. In this study, tensile tests on the joints with double frictional surfaces, the joints with single frictional surface and lap joints have been carried out in order to evaluate the difference of slip and yield resistance among these types of joints. In addition, FE analysis has been carried out in order to clarify the relationship between slip and yield resistance, and influence of slip-yield resistance ratio β and joint length.
