Abstract
In this study, the mechanical joining process for double sheet metals was investigated by using physical modeling method. Process parameters of mechanical joining such as friction coefficient, drawing depth, pouch radius, die radius and material thickness are preliminarily analyzed by finite element method. Referring to the finite element analysis results mechanical joining system is designed on the basis of physical similarities. From the physical modeling test, the effect of process parameters on the deformation for the mechanical joining are experimentally investigated and optimized joining shape that can provide strong joining strength is obtained.
