“…Nowadays, many researchers discuss enhancing material forming quality. Hashemi et al [7] explained about forming limit diagram using an extended strain with the inverse finite element method (IFEM) to generate a rapid calculation for tube length, fluid pressure and axial feeding in tube hydroforming. So IFEM may be turned into a fast simulation method to predict the tube hydroforming parameters.…”

In order to achieve crack free elliptical shape under controlled conditions, an experimental set-up was designed and fabricated. This setup consists of three hydraulic cylinders, an intensifier, a hydraulic power pack, storage tanks, forming die, and all parts are controlled by a Programmable Logic Controller (PLC) system. The elliptical samples can be achieved through proper control of internal pressure and axial force with proper sealing. Experimental work has been carried out with different magnitudes of internal pressure and constrained conditions of axial force. Initially die of elliptical shape has been designed and modeled in Abaqus to successfully achieve the particular shape of the Al6061T4 tube under different internal pressure. The fabricated tube hydroforming machine set-up is highly effective for forming 0.5 mm-2 mm thick Al6061T4 alloy tube samples. The Experimental test has been carried out at 12.7 mm outer diameter, 175 mm length and 0.5 mm thick Al6061T4 samples. Bulge height parameters measured at different points of regular distance gap on the axial direction of the tube length and corner radius found at different pressures range of the samples are plotted under different internal pressures. Samples having an 18.7 mm major elliptical bulge were achieved during the experiment. The experimental data was validated by simulation results.

“…Recently, an increasing number of professionals have explored how to improve forming quality. For example, R Hashemi et al 7 used the inverse finite element method (IFEM) together with an extended strain-based forming limit diagram based on Marciniak and Kuczynski (M-K) theory to develop a fast approach for the estimation of the initial tube length, axial feeding, and fluid pressure in tube hydroforming. The results indicate that IFEM can be used as a quick tool to estimate process parameters in tube hydroforming.…”

Rectangular section parts created through hydroforming have good application prospects in the automotive industry because of their advantages of simple manufacturing procedure, high forming quality, and greater bending module than circular cross-sectional parts. Forming quality is directly influenced by the formed corner parameters of rectangular section parts. It is also a difficult matter in rectangular section hydroforming. The hydroforming rules of an aluminum alloy circular tube are regarded as the research object in this study to investigate the rules of square cross-sectional parts in the hydroforming process. First, the mechanical parameters of the molding material are obtained through experiments. Second, a hydroforming experimental system is self-designed, and tube hydroforming without axial feed is investigated to determine the key parameters of tube forming. Simulation analysis is then conducted for the entire process of tube hydroforming using the nonlinear finite element software DYNAFORM. The finite element model and the correctness of the calculation method are verified by comparing their results with the experimental results. Thereafter, the influence of internal pressure, friction coefficient, and loading path on pipe forming quality is examined. Necessary references are provided for engineering applications.
