G0300-6-3 Implementation of the Tanimura-Mimura's Constitutive Model Covering a Wide Range of Strain Rate and Strain into LS-DYNA and It's Verification Analysis

Abstract

Tanimura-Mimura constitutive model covers a wide range of the strain rates and of a large strain, and enables us to use unified and common material constants to simulate the dynamic behaviors of materials and/or bodies. In this paper, dynamic behaviors of high speed tensile tests and crash test of a full vehicle are simulated by implementing this model in LS-DYNA. Obtained numerical results are in good agreement with the experimental ones and the validity of the model has been demonstrated.
