A theoretical and experimental study on forming limit

Dec 01, 2011 · The tube material was a QSTE340 steel. Additionally, for the tubes used for the forming limit experiments, circular grids with a diameter of 2.5 mm are electrochemically etched on the tube surface before the experiments. Advances and trends in plastic forming technologies for Abstract With the implementation of environmental protection, sustainable development and conservation-oriented policies, components and parts of thin-walled welded tubes have gained increasing application in the aircraft and automotive industries because of their advantages:easily achieving forming and manufacturing process at low cost and in a short time.

Apr 01, 2016 · They found that the difference among the parent material, the HAZ and the fusion zone was apparent and determined that the weld seam width of 60 mm × 4.0 mm (d × t:d-tube outside diameter, t-wall thickness) and 78 mm × 2.7 mm QSTE340 HF ERW tubes were both 0.4 mm and the width of the HAZ of both tubes was 2.4 mm. Li et al. 13 used tensile tests and microhardness tests to Experimental and numerical studies on the prediction of Apr 11, 2012 · For a low carbon steel tube with small wall factor D/t and bending radius R, the over-thinning induced localized necking is one dominant failure in tube numerical control (NC) bending process, which strongly restricts the bendability limit of the tube. In addition, the deterioration of bendability of a tube is increased by the existence of the weak weld region.

Megrendelink számára a Numerical and Experimental Study of Forming Limit The paper establishes the forming limit diagrams (FLDs) for QSTE340 seamed tube hydroforming and the mother sheet metal forming by numerical approach and experimental approach. A novel experimental approach is proposed to evaluate the formability for tube hydroforming under biaxial stretching through elliptical bulging.Then the Nakazima and three types of tube hydroforming tests are simulated QStE340TM automotive structural steel that Doesnincht Rust Steel and Stainless steel are both alloys, meaning they form when metallic elements, two or more, combine with each other to enhance or further develop its properties such as but not limited to reactivity, density, thermal, and QStE340TM automotive structural steel that Doesnincht Rust HSLA Steel Plate High Strength Low Alloy Kloeckner QStE340TM automotive structural steel that Doesnincht Rust A830 steel plate is medium-carbon, structural steel

The welded tube NC bending tests were carried out to evaluate the weld on the formability of the QSTE340 welded tube. The results show that the wall thinning degree, cross-sectional deformation and springback angle increase significantly as the weld line is QStE 340 TM Steel plate,QStE 340 TM Steel pipe - Steel QStE 340 TM EN 10149-2 QStE340TM steel plate / QStE340TM steel sheet, under EN standard, QStE340TM steel plate `s MATERIAL is 1.0974. we can regard QStE340TM steel plates/sheets are low-perlite steel grades offer excellent bending, flanging, cold-bordering and folding properties in both longitudinal and transverse direction.
