U.S.-Korea Cooperative Research: A Combined Analytical Experimental Investigation into Material Formability

这项提案要求资金允许伦斯勒理工学院(RPI)机械工程系李大勇博士与首尔国立大学(SNU)冶金工程系李东宁博士进行为期24个月的研究，板材成形性合作研究项目。这项研究将为RPI在NSF补助金编号下支持的研究增加一个国际合作层面。Dmc-8415309。这项工作的主要目标是开发一种计算机辅助工程(CAE)软件系统，工程师可以在设计阶段使用该软件系统来确定是否可以通过固相成型方法成功制造特定的热塑性塑料部件。在合作项目中，在RPI获得的分析结果及其理论基础将在SNU进行仔细的有效性、准确性和有用性检查。如果在SNU获得的实验结果证明有必要，分析公式将在RPI进行修改。这个项目将结合两个互补的研究团队的人才。其中一个，在RPI，已经开发并正在完善用于预测板材成形极限的CAD/CAE系统。另一个是在SNU，具有分析和测试CAD/CAE系统在预测成形极限方面的有效性的能力。他们合作的产品，一个准确、有效的系统，将对美国和韩国的工程师具有重要价值。合作者是本研究领域备受尊敬的工作者。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。

This proposal requests funds to permit Dr. Daeyong Lee, Department of Mechanical Engineering, Rensselaer Polytechnic Institute (RPI), to pursue with Dr. Dong Nyung Lee, Department of Metallurgical Engineering, Seoul National University (SNU), for a period of 24 months, a program of cooperative research on sheet material formability. The research will add an international cooperative dimension to research supported at RPI under NSF Grant No. DMC-8415309. The principal objective of that work was to develop a computer-aided engineering (CAE) software system which can be used by engineers at the design stage to determine whether or not a particular thermoplastic part can be manufactured successfully by a solid phase forming method. In the cooperative project, the analytical results obtained at RPI and their theoretical bases will be examined carefully at SNU in regard to validity, accuracy, and usefulness. The analytical formulation will be modified at RPI if experimental results obtained at SNU warrant it. This project will combine the talents of two complementary research teams. The one, at RPI, has developed and is refining a CAD/CAE system for predicting the forming limits in sheet materials. The other, at SNU, has the capability for analyzing and testing the validity of the CAD/CAE system in predicting formability limits. The product of their cooperative effort, an accurate, valid system, will be of great value to engineers in the U.S. and Korea. The collaborators are highly respected workers in the field of this research. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
