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.

该奖项将支持Robert Wagoner博士，俄亥俄州立大学和De Mise en Forme des Materiaux，Ecole Nationale Superieure des Mines des Paris之间的合作研究计划。 法国项目负责人是Jean-Loup Chenot博士。 该研究将重点介绍两个实验室中创建的现有有限元计划的比较和开发，以分析工业板形成操作。 结合比较结果的改进计划预计将是此合作的主要产品。 将比较和对比基本公式，编程技术和数值实现。 具体而言，将在三个主要领域进行比较：准确性，计算时间效率和稳定性（或“鲁棒性”）。 将确定和保留每个标准的最佳技术，以构建最终工业用法的更实用的程序。 法国实验室的研究将集中于投入/输出 - 密集测试和开发，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。
