摘 要：In order to verify correctness of two-dimensional axisymmetric finite element model,this paper carries out axial symmetry analysis of the steel ball shell by ANSYS software and 2-D finite element model is established.The radial and tangential stress distribution is acquired,through comparison with the theoretical solution,both are in good agreement.So it is feasible to simulate the three-dimensional model by finite element axisymmetrical two-dimensional model.
