Abstract:
As an advanced technology of sheet metal forming, Hydromechanical Deep Drawing (HDD) is being used increasingly in the sheet metal forming of common materials like aluminum, steel and titanium alloys. In this study, a new method of deep drawing assisted by floating disk is investigated in details for Ti6Al4V both in experimental and simulation. The effects of process parameters on cylindrical cups of Ti6Al4V are discussed. Working pressure curves, which guarantee sound Ti6Al4V work pieces, was founded by series of experimental results. Thickness variation, wrinkling and fracture modes are discussed. Finite element method model by ABAQUSE 6.5 was used to analyze this hydroforming process. NADDRG, Hill-Swift and Aly El-Domiaty theoretical FLD models were used to specify fracture initiation and compared with each other. According to comparisons there is a good agreement between experimental and numerical results.
