Abstract:Three-dimensional DEFORMTM finite element simulations are performed to analyze the plastic deformation of heterogeneous sandwich sheets during rolling. The finite element code is based on a rigid-plastic model and the simulations assume that the rollers are rigid bodies and that the deformation-induced change in temperature during rolling is sufficiently small to be neglected. The rolled product is assumed to comprise a central sheet of either A3003 or A6063 aluminum alloy sandwiched between upper and lower sh… Show more
