Abstract

Abstract: As the impact resistance of metal varies from different material property, therefore, the failure criterion has been adopted as theoretical or empirical formula to describe the capacity of ultimate load and deformation for materials. The paper has improved Johnson-Cook failure criterion equation and identified parameters of failure criterion through combination of experimental data, analogue simulation and numerical fitting, so as to lay the foundation for simulated analysis.
