Effects of material properties on two way tube hydroforming process.

Abstract

    Tube hydroforming method has some drawbacks such as long cycle time and expensive tooling. However, due to continuous improvements in forming process, tooling and lubrication, the method is gaining an increasing acceptance for fabricating complex parts in automobile industry. Tube hydroforming basically is a technical that uses a fluid either to form or aid in forming a part from ductile metal. The effects of material properties and frictions are investigated in the study. The main parameters for strain distribution are anisotropy value and coefficient of friction. The parameters have a major effect on the two way tube hydroforming process. The two way tube hydroforming process becomes meritorious in low anisotropy and/or high friction conditions.
