Abstract: This study presents a novel bulging process for aluminum alloy four-way tubes with solid granules medium. The proposed method aims to enhance forming precision and minimize defects in the internal high-pressure forming process. The behavior of bulging process of aluminum alloy four-way tubes with solid granules medium (SGM) is systematically investigated through comprehensive experimental methodologies. This study explored the critical effects of temperature, back pressure, and associated process parameters on the fundamental forming mechanism. The solid granules medium bulging process successfully produced a four-way tube with an expansion height of 102.14 mm. A three-dimensional finite element method-discrete element method coupling model (FEM-DEM coupling model) is developed based on the uniform load distribution method. The experimental results verified the accuracy of this model, with a maximum deviation of 12.7% between the simulated wall thickness and the experimental data, demonstrating good consistency in the overall deformation pattern.
