The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback. Therefore, evaluation of springback is mandatory for production of precise products. In this paper, the effects of temperature, friction coefficient, blank-holder force and sheet thickness on the springback of AL5083-H111 alloy sheet in warm U-bending conditions were investigated by performing experimental tests and numerical method. ABAQUS FEA software was used for numerical simulation. Finally, comparison of experimental and numerical results showed good agreement.
