| Abstract: | In this paper, the large deformation elastoplastic theory and software of DANY (Study edition) are employed to carry out the numerical simulation research on the process of the locally radial die shaping of seamless steel pipe. The varied laws of the stress-strain on the process are obtained. The results of the numerical simulation are in good agreement with the experiment results by comparing the experimental results. The numerical simulation on research method is proved to be correct. |
