Modeling of the Thickness Variations Arising During Roll-Bonding of Clad Materials

在覆层材料的滚接过程中，有时会产生板厚的空间变化。这代表了在其他相当成功的滚接过程中的一个重大问题。为了理解这一现象，本项目将研究与滚粘接相似的一般条件下界面不稳定性的机制。这项工作的最终目标是建立厚度变化对加工和材料变量的依赖的理论模型。工业合作者的帮助，将提供进行关键实验的设备，将对理论工作形成重要的补充。

Spatial variations in sheet thicknesses sometimes develop during the roll-bonding of clad materials. This represents a significant problem in the otherwise quite successful process of roll-bonding. To understand this phenomenon, this project will study the mechanics of interfacial instabilities under generic conditions which are similar to those of roll-bonding. The eventual goal of this work is to construct a theoretical model for the dependence of thickness variations on processing and material variables. The aid of an industrial collaborator, who will provide the facilities for carrying out critical experiments, will form a significant complement to the theoretical work.
