A novel approach for modeling of anisotropic hardening and non proportional loading paths, application to finite element analysis of deep drawing

Abstract : The modeling of deviations from isotropic hardening is still a difficult task for macroscopic models, in particular for non-proportional loading paths. The alternative polycrystalline models suffer from large CPU time in FE analyses. Due to a specific parameter calibration procedure, a "reduced texture" polycrystalline model with only 8 orientations is in excellent agreement with all experimental curves for a 2090-T3 aluminum sheet. In order to validate the methodology and to evaluate its performance, FE calculations of a deep drawing test have been performed. The CPU time based on the present study is only twice larger than the one with an advanced macroscopic model. The calculated cup heights with six ears are in good agreement with the experimental measurements.
