Evaluation of Plasticity Models Using Uniaxial Tensile Test

摘要: In this study, it is aimed to evaluate plasticity model prediction performance for plastic behavior of materials using a uniaxial tensile test. For purpose, von Mises, Hill-48, Hill-93, Barlat-89 and Hu -2003 models are studied, DC04, DP780, 6000 series aluminum alloy used as materials. Tensile tests performed with three directions (rolling, diagonal, transverse), mechanical properties obtained. addition, anisotropy coefficients calculated by tests. Validation obtained material parameters. Yield locus yield stresses-anisotropy depends on in evaluation models. As result Hu-2003 showed the best modeling all
