“…This choice is due to several reasons. Firstly, that this criterion leads to numerical simulations of the split-ring test which are in good agreement with experimental results at room temperature [20,28]. Secondly, the anisotropy of the yield stress is rather limited even if it is larger for the plastic anisotropy ratios.…”

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.

“…Bu malzemelerden bir tanesi de alüminyum alaşımlarıdır. AA 5754 Al-Mg alaşımları, sahip oldukları yüksek süneklik ve dayanıklılık [6], iyi kaynak edilebilirlik ve düşük yoğunluk gibi özelliklerinden dolayı otomotiv endüstrisi başta olmak üzere yaygın kullanım alanına sahiptirler [7]. Ancak bu alaşımların şekillendirilebilirlikleri, mikroyapıları nedeniyle oda sıcaklığında çelik sac malzemelere nazaran çok düşüktür [8].…”

Abstract. The manufacturing process and the behavior of a sheet formed spring manufactured from an aluminum sheet is described and investigated in this work considering the specifications for the in-service conditions. The sheet formed spring is intended to be applied in car multimedia industry to replace bolted connections. Among others, are investigated the roles of the constitutive parameters and the hypothesis of evolutive elastic properties with the plastic work in the multi-step forming process and in working conditions.
