Author(s): Huang, Xiaodong; Lippmann, Hurst; Lu, Guoxing; Yu, Tong Xi
Abstract: The large deflection of an elastoplastic beam with prescribed moving and rotating end conditions is investigated to simulate its air-bending process. A finite difference model is developed and governing equations in terms of rotations of elements were derived. Due to both geometrical and material non-linearities, only numerical solutions are obtained by using an iteration procedure. Four typical examples with various moving/rotating boundary conditions are shown by graphs. Numerical analyses also show the evolution of the plastic region and the effects of springback and loading path on the deformed profiles.
