US-France Cooperative Research: Field Fluctuations, Microstructure Evolution and Coupled Phenomena in Random Heterogeneous Materials

[0231867] ponte castaneda这项为期三年的美法材料工程合作奖涉及宾夕法尼亚大学、加州理工学院、密歇根大学、法国国家科学研究中心、巴黎综合理工学院和巴黎高等师范学院的研究人员。美国的Pedro Ponte Castaneda和法国的Pierre Suquet领导了一个关于模型复合材料非线性行为的计算和测量的合作项目。他们将研究均匀化问题，包括非线性性质、场波动、微观结构演变和不同材料系统中的耦合物理现象。这项研究是由几个技术问题的应用驱动的。这些包括金属多晶系统的蠕变和成型操作，多孔弹性体的研究，金属基复合材料和智能/活性材料（包括形状记忆合金和铁电体）的高温行为。目标是通过研究组分来预测宏观复合材料的行为。美国调查人员拥有理论专业知识。这是由法国调查人员的实验和数字专业知识补充。该奖项代表了美国方面对NSF和CNRS的平行提案。美国国家科学基金会将支付美国研究员及其学生的旅费和生活费。法国研究中心将支持法国研究人员和学生访问美国。

0231867Ponte CastanedaThis three-year award for US-France collaboration in materials engineering involves researchers at the University of Pennsylvania, California Institute of Technology, University of Michigan, the French National Center for Scientific Research, Ecole Polytechnique and Ecole Normale Superieure. Pedro Ponte Castaneda in the US and Pierre Suquet in France lead a cooperative project on computation and measurement of nonlinear behavior of model composite materials. They will study problems of homogenization, including nonlinear properties, field fluctuations, microstructure evolution and coupled physical phenomena in different materials systems. The research is motived by several applications of technological questions. These include creep and forming operations of metal polycrystal systems, studies of porous elastomers, high-temperature behavior of metal-matrix composites and smart/active materials (including shape-memory alloys and ferroelectrics). The goal is to predict the behavior of macroscopic composite materials by investigating the components. The US investigators have theoretical expertise. This is complemented by the French investigators' experimental and numerical expertise.This award represents the US side of parallel proposals to the NSF and the CNRS. NSF will cover travel funds and living expenses for the US investigator and his students. The CNRS will support visits by French researchers and students to the United States.
