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.

板厚度的空间变化有时在 包覆材料的辊压结合。 这是一个重大的 在其他相当成功的辊压结合过程中的问题。 为了理解这一现象，本项目将研究 在一般条件下的界面不稳定性， 类似于辊压结合。 这项工作的最终目标是 建立了厚度依赖性的理论模型 工艺和材料变量的变化。 的帮助 工业合作者，谁将提供设施， 我们的关键实验，将形成一个重要的补充， 理论工作。
