Abstract

Abstract

By comparing the results of Taylor test and computational simulation, a validating and optimizing method on dynamic constitutive model material constants was proposed. This method was applied to the Johnson-Cook model for OFHC copper and some uncertainty of Taylor test was analyzed. Results show that it is reasonable for validating and optimizing material constants for dynamic constitutive model with this method.
