The mechanical behavior under uniaxial tension of Al–Mg alloy 5182 pre‐deformed in conventional rolling (CR), asymmetric rolling‐continuous (ASRC), and asymmetric rolling‐reversed (ASRR) was investigated and modeled with a rate dependent crystal plasticity finite element method and VPSC (Visco‐Plastic Self Consistent) model. M–K theory combined with Yld2000 model by Barlat et al. (Int. J. Plasticity 2003, 19, 1297) was used to predict the strain‐based and stress‐based formability for AA 5182 material. It was concluded that the new ASRR process has very compatible formability with improved strength compared to CR process. These merits can be directly applied for clam‐shell resistant design in rigid‐packaging industry.
