FEM Simulation of the stretch-forming of aircraft skins
نویسنده
چکیده
The principle of this process is shown in Figure 1. Only one die (the stretch-block) is needed, which contains the shape of the part. The sheet, clamped with two gripper jaws, is formed around the stretch-block, when the grippers move along the given trajectories. Accurately shaped products can be obtained with minimal springback, when stretch deformation is added to the bending deformation of the sheet.

In this paper, the drawing process of multi-layer sheet metal through wedge shaped die has been analyzed using stream function and upper bound method. Typically a sandwich sheet contains three layers of metal, where the outer layers are of the same thickness and material and different from those of the inner layer. In this study, a new deformation model has been introduced in which inlet and ou...
