Study on rotating compression forming of double-layer clad ring considering Coulomb friction

This study uses two FEM simulations based on deform 3D and superform commercial software assuming coulomb friction to explore the plastic behavior in rotating compression forming of double-layer bounded clad ring. The rotating compression forming can reduce the compressive force and make the deformation uniform. Effects of the frictional coefficient, shear yield stress ratio, rotating angular velocity, frictional coefficient ratio, clad ring height ratio etc on compression characteristics including the effective stress, the effective strain, the velocity field, the shear strain, the compressive force etc. are investigated effectively. Moreover, the realistic rotating compression experiments of clad ring have been carried out to verify the acceptance of both FEM simulation models.
