Rubber based forming process is a versatile metal fabrication process used in commercial aerospace, automotive and defence applications. It is well suited for prototyping and production of small quantities of sheet metal parts. Rubber based forming employs a rubber pad contained in the rigid chamber or flexible diaphragm as one tool half, requiring only one solid half to form a part to final sh...

The investigation into the circumferential mechanical properties of tubular materials has been receiving increasing attention, since tube hydroforming process used in forming field, because have a significant effect on hydroformability materials. In present study, method for evaluation with flaring test was proposed. expressions yield stress, strain hardening coefficient and exponent values wer...

forming limit curve (flc) is an important tool for evaluation of formability of sheet metals subjected to different loading. free bulge of aluminume tubes has been investigated numerically to obtain flc. to verify the numerical results one experimental setup has been manufactured which has the ability of controlling the internal pressure and axial feed. in this study, time and zone of bursting ...

With fluid forming processes getting more and more common in industrial application a lot of research is carried out to analyze the forming behavior of sheet metal within these processes. In order to gather experimental information about the forming behavior of the workpiece, an imaging system is presented, that will allow determining the actual shape within the forming process. The system has ...

Aluminum and magnesium alloys are of materials for decreasing vehicle weight and consequently reducing fuel consumption. However, forming limitations regarding their low formability at room temperature are found when being manufactured by conventional forming processes. For this reason, development of new forming techniques, such as warm tube hydroforming, is needed to overcome such limitations...

The widely adopted the high strength steel tube is an important way to solve lightweight body and collision safety. traditional pressure hydroforming hot gas forming through “expansion” deformation form hollow parts, internal driving force. There are some industrial difficulties such as heavy dependence on pressure, wall thickness thinning low production efficiency, which limits application of ...
