Abstract：

In sheet metal hydroforming, the stress state of the plate will be influenced by fluid pressure, which can effectively improve the forming performance of the sheet. To study the change law of sheet metal forming properties under fluid pressure, uniaxial tensile processes of aluminum alloy 2024 under different fluid pressures were numerically simulated by finite element software ABAQUS, and the influences of the fluid pressure on the sheet Mises stress distribution, axial stress distribution, elongation and neck shrinkage were obtained. The results show that under the action of fluid pressure, the deformation of the plate is more uniform, and the plate shows more deformation potential with the increase of fluid pressure, which can achieve a larger elongation.
