Numerical simulation of the anisotropic behavior of 2017 aluminum alloy

In this work, the anisotropic mechanical behavior of 2017 aluminum alloy at room temperature is investigated. An updated version of the multi-mechanism model type devoted to the description of the material anisotropy is then proposed. The prediction of the model is evaluated by considering strain controlled tests under proportional and non-proportional loadings. A special attention was paid to the identification of the material parameters related to the description of the anisotropy and of the isotropic hardening material parameters devoted to the proportional and non-proportional hardening. The proposed multi-mechanism model successfully describes the anisotropic behavior of the material under proportional and non-proportional loading.
