US-France Cooperative Research: Comparison and Development of Finite Element Modeling for Sheet Forming Analysis

该奖项将支持一项合作研究计划， 俄亥俄州州立大学的罗伯特·瓦戈纳博士和 国立材料成型研究中心 巴黎矿业公司。 法国项目负责人是博士。 让·卢普·切诺 研究将侧重于比较， 开发现有的有限元程序创建在两个 实验室来分析工业板材成形操作。 结合比较结果的改进方案是 这将是此次合作的主要成果。 基本 公式，编程技术和数值 将对实现进行比较和对比。 具体地说， 这些方案将在三个主要方面进行比较：准确性， 计算时间的效率和稳定性（或“鲁棒性”）。 将确定每项标准的最佳技术， 为了构建一个更实用的程序， 最终工业应用。 法国实验室的研究将侧重于输入/输出- 密集的测试和开发，而美国的工作将 强调大规模计算，以利用 每个站点的特殊优势。

This award will support a cooperative research program in metallurgy between Dr. Robert Wagoner, Ohio State University and the Centre de Mise en Forme des Materiaux, Ecole Nationale Superieure des Mines des Paris. The French project leader is Dr. Jean-Loup Chenot. The research will focus on comparison and development of existing finite element programs created in the two laboratories to analyze industrial sheet-forming operations. Improved programs incorporating the findings of the comparison are expected to be the principal product of this cooperation. Basic formulations, programming techniques, and numerical implementations will be compared and contrasted. Specifically, the programs will be compared in three principal areas: accuracy, efficiency of computation time, and stability (or "robustness"). The optimum techniques for each criterion will be identified and retained in order to construct a more practical program for eventual industrial usage. Research at the French laboratory will focus on input/output - intensive testing and development, while the U.S. work will emphasize large-scale computations to take advantage of the special strengths of each site.
