Abstract: Aiming at the problem that the shearing quality of disc shearing strip is not high, some complicated phenomena can not be explained effectively by analytic method or experimental method, according to the deformation characteristics of shearing strip process, based on the theory of finite element analysis, the finite element analysis model of disk shear cutting strip edge was established by ANSYS/LS DYNA , and the elastic plastic finite element analysis was carried out on the dynamic shear process of strip. Through the calculation and analysis, the stress and strain distribution of the strip during the fracture process was obtained, the variation law of the shear force during the shearing process and the movement state of the waste edge during the shearing process were derived, and the finite element method was used to calculate the shear. The results indicate that the effectiveness of the shear force is consistent with the actual shear process, and the finite element simulation results are reliable and can be used as the basis for the disc shearing design.
