In recent years, the hydroforming due to reduction in weight and increase in strength of automotive parts has attracted attention of the automotive industry. Thus, the knowledge of the process to produce parts with desired quality and accuracy has been growing. One of the effective methods in improving the formability in the hydroforming is known as pulsating hydroforming. However, the reason of improvement of formability in pulsating hydroforming is still unclear for the closed-die hydroforming of tubes. In this study, the pulsating hydroforming of tube with box die was simulated by the finite element method to examine the effect of pulsating pressure on improvement of formability. In addition, the calculated results are compared with experimental results and it is shown that the improvement of the formability occurs before contact of the tube and die in expansion zone of the tube. Thus, it can be obtained from the results, that the main reason of improvement of the formability is due to the deformation behavior before start of contact of the tube and die. Manuscript profile

One of the most important parts of power transmission in automotives is C.V. joint, which consists of four components where exterior bowl is one of them. Due to its complexity, and importance in automobile and existence of high stresses, forging process is the only cost effective method of production. Hence, the best method of production of this part is forging process. The exterior part of C.V. joint is produced through two subsequent stages. First, forward extrusion is applied followed by backward extrusion. In this research hot forward and backward extrusion of C.V. joint of PRAID with pre-heating while heat loss has taken into account, were simulated using finite element method. The Arbitrary Lagrangian-Eulerian method was employed to improve element distortions. Dies were considered as solid and elastic to investigate the thermal interactions of dies and the work piece. Deformation behavior, die contact pressure and punch force have been discussed by using the numerical results. Force diagrams during forging process according to die displacement and related results are discussed. Numerical results are compared with theoretical results for validation, meanwhile the comparison results are in good agreement. Manuscript profile

Abstract: Electromagnetic forming and high speed hydroforming are two new methods of tube formin. In this research, the results of expansion forming of tubes using electromagnetic forming and high speed hydroforming are compared by numerical modeling. In this study, firstly, the results of numerical solution of electromagnetic forming process in ABAQUS software are compared with experimental test results of other references. Then, results of numerical solution of high speed hydroforming in Abaqus software are compared with experimental test results. Finally, these forming methods are compared with each other in terms of displacement and thickness distribution. There is good agreement on bulge tip displacement results obtained by experimental tests and the results of numerical simulation. The results show that forming and deformation of electromagnetic forming process has been far faster than high speed hydroforming. However, a high speed hydroforming can be used in applications such as fitting of rings on tubes instead of electromagnetic forming.

Abstract: In this paper, the results of experimental and numerical simulation of low velocity impact process have been carried out to investigate energy absorption of composite sandwich panels with 3D woven fabrics of glass fibers and epoxy resin. For this purpose, diagrams of force-displacement of the quasi-static and quasi-dynamic impact tests were studied. For the finite element simulation, Sandwich panel is considered as a composite material with anisotropic elastic properties. In this simulation, Hashin’s damage criteria have been used to model the fracture mechanics. The energy absorption in quasi-dynamic test is greater than the quasi-static test. Comparison of the numerical and experimental simulation shows good agreement between the results.Keywords: 3-Dimensional reinforcement, Impact behavior, Finite element analysis (FEA), Lay-up (manual/automated) Manuscript profile

Single point incremental forming (SPIF) and fuseddeposition modeling 3D printing (FDM) are two methods of rapid prototyping. Each method has its own pros and cons. using SPIF method can provide an accurate forming process to shape sheets fabricated by 3D printing with their special characteristics. In this study, single-point incremental forming of Poly Lactic Acid (PLA) sheets fabricated by FDM 3D printer was investigated by experiments. The formability process was evaluated by two different experiments. In the first experiment, a lubricant was used at ambient temperature and SPIF was investigated and for the second experiment hot air and lubrication were employed to achieve better formability. In addition, the effects of sheet thickness and strategy of layering of printed sheets by FDM were also studied on SPIF formability. The results showed that the incremental forming of printed PLA sheets in hot air is a more successful state to produce dome shapes parts and ruptures are less and this forming method can be used for some applications such as making partial curve of skull as a medicine solution in surgeries. Also, it was shown that the best layering strategy to print the PLA sheets used for better forming of SPIF is triangular pattern strategy against with rectangular strategy. It was found that thickness of 2mm printed sheet has better formability and less rupture versus 3mm of thickness. Manuscript profile
