Determination of Constitutive Model Constants From Cylinder Impact Tests

Abstract

This report describes and evaluates two computational strength models: The Johnson-Cook model and the Zerilli-Armstrong model. The models are compared to tension and torsion data, and to cylinder impact test data. Various techniques to obtain constants for the models from cylinder impact test results, are also presented.
