..., an innovative mechanical joining process via a hydroformed threaded coupling is proposed to achieve the successful joining of a metal–plastic composite layered tube (CLT). For the threaded connection, the CLT with an internal thread to act as a sleeve and the coupling tube with an external thread to act...

... profiles: increasing and decreasing profiles), and several temperature levels (ambient up to 260 °C). Additional warm hydroforming experiments were conducted using a closed-die set up to understand the forming limits of AA5754. The results from tensile and hydraulic bulge tests as well as closed-die...

...Muammer Koç; Ali Agcayazi; John Carsley The warm sheet hydroforming process was investigated to determine the optimal process conditions of temperature, pressure, and pressurization rate for maximum formability of AA5754-O using an experimental stretch forming die shape. The optimal process...

...L. M. Smith; J. J. Caveney; T. Sun A family of closed-form formulas for calculating minimum corner-fill radii in planar sections of tube hydroformed products is introduced. Corner forming limit diagrams relating the limiting major strain to the minimum corner-fill radius are introduced. The theory...
