This study deals with the mechanical behaviour and material modelling of an AA5754‐O alloy at elevated temperature. Experimental shear tests were performed from room temperature up to 200°C, and the material behaviour has been identified with both shear and tensile tests, as a function of temperature. To analyse the influence of temperature during forming over springback, a split‐ring test is used. Experimental results are obtained and compared to numerical simulations performed with the finite element in‐house code DD3IMP. The numerical process of ring splitting is performed with the in‐house code DD3TRIM. The main observed data are force‐displacement curves of the punch during forming, cup thickness at the end of forming, and ring gap after splitting. It is shown that all these parameters are strongly dependent on the forming temperature. A correlation is obtained between experimental data and …
