0233313SoomThis three-year award for US-France collaboration in mechanical engineering involves researchers and students at the State University of New York at Buffalo and the University for Science and Technology in Lille, France. Andres Soom and Gary F. Dargush in the US and Jacky Lesage and Gerard Mesmacque in France will lead this collaborative program to model the tribological performance and failure of thin coatings and films. In particular, they will conduct a series of experiments, resulting in patterns of wear or film failure. In parallel, computational mechanical modeling of 3D contact stresses and strains will be developed. The US investigators are expert in computational, contact mechanics and tribological testing. This is complemented by French capabilities in characterization, preparation and failure of thin films, and nano-indentation measurements. Thin films and coatings are frequently used to enhance performance and durability of mechanical components and production tooling where some sliding occurs at contact with the surface. Recently advanced designs of surfaces have challenged current ability to design films, and predict behavior, based on mechanical properties. This joint effort will advance understanding of life-cycle performance and predictive modeling. This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigators and graduate student. CNRS will support the visits of the French researchers and graduate students to the United States.

0233313 Soom这个为期三年的美法机械工程合作奖涉及布法罗的纽约州立大学和法国里尔科技大学的研究人员和学生。 Andres Soom和加里F.美国的Darfish和法国的Jacky Lesage和Gerard Mesmacque将领导这一合作项目，以模拟薄涂层和薄膜的摩擦学性能和失效。 特别是，他们将进行一系列实验，得出磨损或薄膜失效的模式。 同时，将开发三维接触应力和应变的计算机械建模。 美国研究人员是计算、接触力学和摩擦学测试方面的专家。 法国在薄膜的表征、制备和失效以及纳米压痕测量方面的能力对此进行了补充。薄膜和涂层经常用于提高机械部件和生产工具的性能和耐用性，其中在与表面接触时发生一些滑动。 最近先进的表面设计已经挑战了当前基于机械性能设计膜和预测行为的能力。 这一共同努力将促进对生命周期性能和预测建模的理解。 该奖项代表了美国方面向NSF和法国国家科学研究中心（CNRS）提出的联合建议。 NSF将支付美国研究人员和研究生的旅费和生活费。 CNRS将支持法国研究人员和研究生访问美国。
