Bulging Deformation Prediction and Experimental Verification of Bonded Double-Layer Clad Cylinder in Rotating Compression

Article Preview

Abstract:

The objective of this study is to establish three analytical models including the Upper Bound Method (UBM), the Slab Method (SM), and the Finite Element Method (FEM) for the rotating compression of bonded double-layer clad cylinder. As for the prediction of bulging deformation, apart from the FEM simulation, the other hybrid method can combine the UBM with an elliptical curve-fitting method for predicting compression force and bulging deformation. Meanwhile, the compression force and bulging deformation between analyses and experiment are compared to validate the correctness of the models. These models established can be offered to the reference of metal forming industries.
