Simulation of the rolling process of a laminated composite AMg3/D16/AMg3

Introduction. Over the past decades, laminated composites based on aluminum alloys have been increasingly used in aerospace and automotive industries. Laminated are usually produced by accumulative roll bonding, which results metallurgical bonding of initially prepared sheets. Hence, main task is to obtain a reliable bond between materials. However, at present, process joining similar or dissimilar materials plastic deformation still poorly understood phenomenon. In this regard, recent years, methods finite element modeling processes begun develop intensively. The purpose work establish relationship stress-strain state parameters formation stable different compositions. To achieve goal, following tasks formulated: 1. Simulation composite “AMg3/D16/AMg3” rolling using data corresponding physical experiments carried out Institute Engineering Science Ural Branch Russian Academy Sciences; 2. Selection analysis most important process. Research methods. Process simulation system Deform-3D was chosen as research tool. Results Discussion. An coordinate grid distortion velocity vectors material flow layers revealed that distributed inhomogeneously cross section after rolling: outer more intensively compared middle layer. maximum scatter strain intensity ei section, observed reduction ratio 75%, 12%. This allows one accept for analytical calculations first approximation assumption uniformity. A established beginning threshold expansion contact surface normal pressure interlayer boundary. final part study, future directions improving approaches proposed.
