Evaluation and Correlation of Dynamic Flow, Failure, and Microstructural Properties of Heat-Treated 4130 Steel

Abstract

An experimental program has been carried out in conjunction with the University of Dayton Research Institute tocharacterize the material constants of the Johnson-Cook constitutive and damage models, and additionally, themicrostructure of the failed specimen has been investigated to observe any association of deformation micromechanics tothe phenomenological development of the Johnson-Cook expression. An Analysis of Variance (ANOVA) statisticalanalysis was carried out to identify whether temperature or strain rate were signixC;cant factors in causing changes tomicromechanical features, and if so, whether the micromechanical properties were related to the Johnson-Cookparameters.
