“…7) can be fitted best to the experimental data for austenitic stainless steels [12,20] for IN 718 [21] and for SS 304 [7], while for aluminum alloys, the Hollomon hardening law (Eq. 8) was reported to give the best fit [22]:…”

“…In the model, a surface-to-surface contact algorithm was applied to the interface between the tube and the die with Coulomb's friction set to 0.05 in accordance with different reported values in the literature for an unlubricated condition [4,22]. To mimic the experimental loading conditions in the FE model, the internal pressure was applied on each element of the meshed tube and increased linearly, while fixing the end nodes of the tube to emulate the no end feeding condition used during the free expansion process.…”

Generally, the mechanical response is defined by the stress-strain behavior that can be determined from tensile testing of the specimens extracted either from the sheet used for roll forming of the tubes or directly from the tubes. More recently, free expansion testing has been used to characterize the mechanical response of the material for hydroforming applications. The free expansion test can emulate process conditions similar to those found during THF, and as such, can be used to obtain reliable and accurate information on the mechanical response/properties of the tubular material. The aim of this research is to present an approach for evaluating the s...

“…The latest studies are devoted to the mechanical and numerical modelling of the hydroforming processes using the finite element analysis [6][7][8][9][10], allowing the prediction of the material flow and optimisation of hydroforming parameters [11][12][13][14][15][16][17][18][19]. In addition, the accuracy of the numerical a Corresponding author: bouchaib.radi@yahoo.fr prediction remains linked to the fidelity models representing the behaviour of the WT and particularly the mechanical properties (plasticity metal flow, anisotropy effect and damage initiation and growth) of the base metal (BM) and the welded joint (WJ) zone [20][21].…”

-This paper presents an experimental/numerical methodology which aims to improve 3D welded tube considering their anisotropic effect, geometrical singularities found in the welded joint, and heat affected zone behaviour by hydroforming process. This process contributes to reduce the number of welding and assembly operations needed to generate complex structures, while improving the weight saving and quality of finished parts. In spite of the advances in the performance of this manufacturing technology, some problems are linked to particularities of certain raw materials and additional studies must be developed, like in the case of welded tubes. The experimental study is dedicated to the identification of stress-strain flow of the base metal and the heat-affected zone from the global measure of tube displacement, thickness evolution and internal pressure expansion. Nanoindentation test is adapted to investigate the heat affected zone mechanical behaviour. Workpiece behaviour's models used to simulate the expansion tests, made it possible to highlight the combined effects of the inhomogeneous behaviour of basic material and heat affected zone, as well as the geometrical singularities found in the welded tubes. From the simulations carried out, it is clear the influence of the plastic flow behaviour of the welded tube in the final results (thickness distribution, stress instability, tube circularity, critical thinning and rupture).
