Abstract

Abstract

A multi-stage computational inverse technique is presented to determine the dynamic constitutive parameters of concrete based on the split Hopkinson pressure bar tests at different strain rate loadings.In this method, sensitivity analysis for parameters is carried out based on different experimental models and classification for the parameters is performed according to sensitivity, then the parameters are determined step by step through the inverse method.During parameters identification by multi-stage inverse method, last identified results are applied to current parameters identification.The results indicate that this method obtains the parameters rapidly, which are determined difficultly and expensively by traditional method, combining with different experiments.It is a potentially effective and useful tool to identify material constitutive parameters.
