Experimental and Numerical Investigations of Push Bending of Copper Thin Walled Tubes

Abstract

In order to realize the successful process of forming the thin walled tubes in different industries, numerous methods have been registered by researchers. The tube push bending technique is a new process which allows forming tubes with lower bending ratio. In this study, the effects of push bending process on thickness variation and stress distribution are investigated. In addition, experimental and analytical studies have been dealt with in order to evaluate different bending radii. Results show close congruity between experiment and simulation.
