Deep drawing process of steel/brass laminated sheets

In this paper, the effects of several parameters on the deep drawing process of laminated sheets are comprehensively studied. The main reason to carry out such a process is taking the advantages of different materials, such as high strength, low density and corrosion resistibility, at the same time and in a single component. With this regard, it is possible to take the benefits of the forming processes, such as low waste of material and high directional strength of the components. This research work is concerned with the experimental and finite element studies of the deep drawing process of steel/brass laminated sheets. Several tests were conducted to investigate the influences of some variables, such as the stacking sequence of the layers, lubrication, blank-holder force and the diameter of the composite blank on the load–displacement curve and the final shape of the produced components. Investigation of stress and strain distributions in the deep drawn cup were also done and the FE results showed that the numerical method can predict the same place of tearing for bimetal cup as occurred in experimental tests. The main issues studied in this work are the material flow (occurrence of defects such as wrinkling and fracture) of the layers of the specimen and the required drawing force.
