Abstract A finite element model is established to simulate the hot bending process of titanium alloy sheet by using
ABAQUS software. The stress and strain distribution and the influence of process parameters on the forming process are
analyzed. The results indicate that deformation distribution mainly concentrates at the center position of the thickest area.
When the new contact position appears between the upper die and the sheet, the forming sheet enters the correction bending
phase and the forming force increases sharply. When holding 600s, the maximum springback displacement and the upper
die forming force reduces 84% and 94%, respectively. The simulated result shows a good agreement with the deformed part
at the same conditions.
