Analytical modelling of tube hydroforming

open access: yesThin-Walled Structures, 1999
The automotive industry has shown a growing interest in tube hydroforming during the past years. The advantages of hydroforming (less thinning, a more efficient manufacturing process etc.) can, for instance, be combined with the high strength of extra ...

Theoretical and experimental analysis of stroke-controlled tube hydroforming

open access: yesMaterials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2000
To select tube hydroforming instead of conventional fabrication, one has to know the tube material behaviour and tribological effects during hydroforming and how the hydroforming operation itself should be controlled. The hydroforming operation is either

Developments in hydroforming

Journal of Materials Processing Technology, 1999
Abstract A brief review of recent developments in the hydroforming processes is presented. The process variations used for forming tubular and flat components, the integral hydrobulge forming of shell products and the newly developed viscous pressure forming process are outlined and their characteristics and applications are summarized, especially in

Formability of Micro-Tubes in Hydroforming

AIP Conference Proceedings, 2011
Micro‐hydroforming is a down‐scaled metal forming process, based on the expansion of micro‐tubes by internal pressurization within a die cavity. The objective of micro‐hydroforming is to provide a technology for the economic mass production of complex shaped hollow micro‐components.

Study of optimizing a tube hydroforming

2016 4th IEEE International Colloquium on Information Science and Technology (CiSt), 2016
The shaping by hydroforming process involves several complex phenomena and presents several types of nonlinearities (geometric, material,…). The development of a hydroforming operation requires a lot of testing to determine with precision the optimum loads of trips and get a room without defects.

Magnesium tube hydroforming

Materialwissenschaft und Werkstofftechnik, 2008
AbstractMagnesium alloys reveal a good strength‐to‐weight ratio in the family of lightweight metals and gains potential to provide up to 30 % mass savings compared to aluminium and up to 75 % compared to steel. The use of sheet magnesium alloys for auto body applications is however limited due to the relatively low formability at room temperature ...

Fluid ‘hydroforming’

Journal of Applied Chemistry, 1954
AbstractFluid ‘hydroforming’ is a powdered catalyst operation that owes its success to continued research and development on naphtha‐upgrading. Its predecessor, fixed‐bed ‘hydroforming’, was employed commercially to make aromatics and aviation gasoline during World War II.

Bursting for Tubular Hydroforming

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">Tubular hydroforming provides a number of advantages over conventional stamping processes, including reduction in part counts and weight reduction, improved strength and stiffness of structural components, lower tooling costs, and higher dimensional accuracy.
