Prediction of flow curves and forming limit curves of Mg alloy thin sheets using ANN-based models

► Flow curves and forming limit curves of AZ31 Mg alloy thin sheets were predicted by ANNs. ► The effect of temperature, strain rate and fibre orientation was investigated. ► The capability of ANN was evaluated by comparing experimental and predicted curves. ► The ANN performance was quantified by average absolute relative error and correlation coefficient. ► Predicted and experimental curves were in excellent agreement both in terms of shape and values.
