Abstract Hydroformed parts are widely used in industrial automotive because of their higher stiffness and fatigue strength reduced weight relative to corresponding cast welded parts. This paper reports a hydraulic-forming experimental platform for rectangular tube fittings that was constructed conduct an experiment on the hydraulic forming fittings. A finite element model established basis flui...

Abstract Large deformations under in-plane compression of paperboard appear in forming processes like hydroforming, pressforming and deep drawing, but the mechanisms deformation have not been studied on a micromechanical level. A constrained test is presented. This allows for compression, buckling, wrinkling compaction. The realized using DEBEN CT-500 in-situ tester laboratory microtomography s...
