In recent years extruded sections of aluminum alloy have been applied to structural parts, such as the space frames of automobiles. Generally speaking, a secondary forming process, such as bending, is required when these materials are used in these applications. The author has investigated the springback of extruded sections subjected to bending moment by experimentation and simulation. Quasi-uniform bending apparatus, without any tools for preventing the flattening distortion, and with a mandrel, was performed. A uniform bending process was simulated by the Finite Element Method (FEM) in order to obtain the springback.
