Slab analysis, FEM simulation and experimental verification on rotating forging of three-layer clad cylinder with constant shear friction

Abstract

This study establishes the slab analytical model and finite element simulation in the rotating forging of three-layer clad cylinder. The commercial finite element software is used to explore effectively the effective stress, effective strain, velocity field, forging force and rotating torque in the rotating forging of the three-layer clad cylinder. An analytical approach based on the slab method is used to derive the vertical stress, the whole radial stress, the radial stress for each layer, the shear stresses at the interface, the forging force and the rotating torque. Moreover, the rotating forging experiment of the three-layer clad cylinder is carried out practically to measure the forging force and the outer surface of the three-layer clad cylinder. Forging forces among slab analysis, FEM simulation and experiment are compared with each other to verify the acceptance of these models. This study can be offered to industries for technology establishment of rotating forging.
