This paper presents the results of the numerical multi-axial material tests for predicting elastoplastic deformation behavior of aluminum alloy sheets under equi-biaxial tension and in-plane tension-compression stress states. In this study, we have performed the numerical biaxial tensile and tension-compression tests of a 5000-series aluminum alloy sheet using the crystal plasticity finite element method based on the mathematical homogenization method which has been developed by the previous studies. We found that the true stress-logarithmic plastic strain (SS) curves calculated by the numerical biaxial tensile test slightly deviate from those measured by the biaxial tensile tests using a cruciform specimen. On the other hand, the results of the numerical tension-compression test demonstrated that the predicted SS curves shows a reasonable agreement with those obtained by the experiment using the biaxial stress-testing machine with comb-shaped dies.
