Abstract：

To explore the high inner pressure hydroforming characteristics of 5083 alloy straight T-shape tube, firstly the hydroforming situation was studied by FEM numerical simulation. Secondly, the distribution of wall thickness, strain and stress of the tube were investigated and the reason how the tendency of wall thickness distribution formed was explained using the change of strain and stress during the forming process. The simulation results show that a thickness reduction happens on the top of pipe branch, the thickness in the original part and the punch-contacting part of the tube increases. The experimental results are approximately in accordance with the simulative ones in the aspects of the geometry size and thickness distribution during the 5083 alloy T-shape tube hydroforming process.
