Webhydroforming processes, basic stress and strain considerations may contribute further to understanding the material aspects of hydroforming compared to the traditional stamping of sheet metal automotive panels. Most sheet metal panels are produced at a high production rate using rigid tools with a fixed pre-determined final surface. WebIf the hydroforming process does not result in a change in the length of the pre-formed tube, then the only change is an increase in the local section diameter. This corresponds …

It is evident that the aluminum tubes, extruded or seam-welded, generally have considerably lower formability than steel tubes in hydroforming. This is an important factor which needs to be addressed via proper product design and process optimization. MECHANICAL PROPERTIES free online 3d drawing

Web1 okt. 2004 · Analytical studies on onset of bursting failure in tube hydroforming under combined internal pressure and independent axial feeding are carried out. Bursting is irrecoverable phenomenon due to local instability under excessive tensile stress. There are three types of test methods such as free bulging and elliptical bulging, hydroforming limit test. These test methods were applied on laser welded and electric resistance welded tubes (ERW). The cracking failure defect has been analysed on both seamed and ERW tubes during bulging of tube.
