Springback Behavior of AA6082T6 Tubes in Three-point Bending Operation

Springback is an inevitable phenomenon in bending operations. For the geometrical accuracy in manufacturing, springback should be predicted and a required compensation should be applied to the operation. The numerical method is a very popular approach to predict the behavior of material in the operations. This method provides the reduction in time, effort and costs in comparison with the trial and error method. In this study, springback in the three-point bending operation of AA6082T6 tubes is investigated. A numerical model is established, and results are compared with experimental outputs for verification of the model. Effects of the indenter travel distance and a wall thickness of a tube in springback are studied.
