本文综合研究了几个参数对层合板拉深成形过程的影响。进行这种工艺的主要原因是同时在单一部件中利用不同材料的优点，如高强度、低密度和耐腐蚀性。在这方面，可以利用成形工艺的优点，例如材料的低浪费和部件的高定向强度。本文对钢/黄铜复合板的拉深成形过程进行了实验研究和有限元分析。进行了几项试验，以研究一些变量的影响，如层的堆叠顺序，润滑，压边力和复合材料坯料的直径上的负载-位移曲线和生产的部件的最终形状。研究了拉深杯形件的应力应变分布，有限元结果表明，该数值方法可以预测拉深杯形件的撕裂位置，与实验结果一致。在这项工作中研究的主要问题是材料流动（发生缺陷，如起皱和断裂）的层的试样和所需的拉拔力。(c)2012爱思唯尔有限公司保留所有权利。
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. (c) 2012 Elsevier Ltd.
