Study of the Stress and Strain for Shaft Parts by Cross Wedge Rolling

Apply the finite element software of ANSYS/LS-DYNA to simulate the rolling process of pairs of cross wedge rolling shaft and to analysis the stress field of the rolling at the stage of stretcher and to analysis the distribution of strain field. what´s more, it can make a clear analyss of the metal´s situation such as the under force and the movement at the process of the rolling deformation, it has provided a good foundation for cross wedge rolling theoretical research and technological dlopment in the future.
