Abstract
The influence of the springback in high strength TA18 tubes on the wall thinning and section distortion under different process parameters was investigated using ABAQUS Explicit/Standard finite element models. The results show that the wall thinning ratios after unloading-springback are less than 10% under different process parameters for high strength TA18 tubes, while the section distortion ratios after springback are more than 35%, even 60% except a few measured points. The "platform" of section distortion ratio at stable forming zone disappears after springback.
