“…Tzou et al [8] used SUPPERFORM to simulate the rotating compression forming of double-layer bounded clad cylinder under constant shear friction, and compare its results with experiment. Tzou et al [9] proposed a new piercing technology with rotating punch on the double-layer clad sheet; it carries out an FEM simulation on rotating piercing process using DEFORM-3D commercial software under Coulomb friction. Tzou et al [10,11] proposed a hybrid technique combining UBM with an elliptical curve-fitting method to predict both the compression force and the bulge profile in non-rotating and rotating one-layer cylinder compression forming.…”

The friction caused power losses and bulging deformation are always inevitable. The rotating compression forming can reduce the compression force and bulging deformation in metal forming. Furthermore, the bounded double-layer metal material is able to have advantage in proper material cost saving and meeting the required strength for customer. Accordingly, this present study proposes the analysis based on Slab Method (SM) and Finite Element Method (FEM) under constant shear friction to predict the compression force and the rotating moment in the rotating compression forming. Moreover the bulging deformation profiles, the effective stress, the effective strain, the velocity field, the compression force, the rotating moment, and the twist angle can be obtained from FEM simulations. It is also shown that the predicted results have the same trend to verify the acceptance of analysis models.
