“…The warm forming process is intended to overcome this problem by using an elevated forming temperature which is below the recrystallization temperature (Tebbe and Kridli, 2004). A typical warm forming experimental set-up is shown in Fig.…”

“…This leads to recycling issues, since aluminium alloys need to be separated by alloy series in order to produce better-quality recycled alloy. Therefore, the elimination of the appearance of surface marks in Al-Mg aluminium can lead to their use in outer automotive panels and improve their recyclability [13].…”

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 numerical simulation for the evolution of punch force and opening after springback as a function of temperature. The distribution of the tangential stress in the cup wall is the main factor influencing the springback mechanism in warm forming condition.

“…There is no available literature on the behavior of strain ratios or anisotropy at elevated temperature. It may be due to the developments in the warm deep drawing operation started recently [3][4][5][6] and these properties will be required only when finite element models of the warm forming operations is developed.…”

Anisotropy and strain rate sensitivity index (m) plays a very important role in the formability of materials. In the present investigation strain ratios in 0°, 45°and 90°t o the rolling direction and the strain rate sensitivity index were calculated at different temperatures. After developing the data from experiments, Artificial Neural Network (ANN) models are trained for different properties. Trained ANN models are used to calculate different strain ratios and sensitivity index at unknown temperatures. The results are promising and the percentage error in ANN prediction is found to be around 10%.
