The Sharp Indentation for Identifying Constitutive Relationship of Metallic Materials

Abstract:

Article Preview

Based on a series of tests and elastic-plastic contact finite element analyses, a sharp indentation method for predicting the constitutive relationship of metallic materials was presented. Dependent on the dimensionless linear relationship which is independent of the hardening index n, a forecasting formula of constitutive parameters can be gotten and its form is much terser. The test results and finite element calculations show that, the predicted stress-strain curves are in agreement with the uniaxial tensile test results. The validity and precision of this method was certified by in-dentation tests on kinds of different materials.
