Reliability analysis of tube hydroforming process
In this paper, we propose a reliability–mechanical study combination to treat the tube hydroforming process (THP). This process consists to apply an inner pressure combined to an axial displacement to manufacture the part. Our goal is the computation of the failure probability of the hydroforming process. Normally, this process is particularly complex and have to be solved numerically. There ar...
متن کاملSimulative Analysis of Tube Hydroforming Process
The tube hydro forming process (THF) is an unconventional metal forming process, where in tube is deformed internally and thus it is forced to expand and conform to the shape of the surrounding die. The performance of this process depends on various parameters like internal pressure, axial loading etc. For FEA simulation, it requires proper combination of material selection, part design and bou...
متن کاملTheoretical and experimental study on the hydroforming of bifurcation tube
Hydroforming is one kind of plasticity working, which can be used to increase the diameter, to change the geometry, or to expand the outer walls of cylindrical shells or tubes. The forming principle of hydroforming is by using a die to constrain the outer geometry of a tube and then pumping high pressure oil into the inner tube, so as to force part of the tube to flow into the die cavity. In or...
متن کاملLoading Path Determination for Tube Hydroforming Process of Automotive Component Using APDL
In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. This adaptive simulation technique is based on the ability to detect the onset an...
متن کاملAn analysis of the contact between the stent and the artery using tube hydroforming simulation.
Stents for angioplasty have been extensively used to treat coronary diseases. The aim of this study is to analyze the expansion of the stent and the contact with the artery using tube hydroforming simulation. In the simulation, the contact stress and the final shape of the artery after stent expansion process using the Stampack (®;) software will be studied. A model of a commercial stent made o...
