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.

该奖项将支持俄亥俄州立大学罗伯特·瓦格纳博士与巴黎高等矿业学院材料冶金研究中心在冶金领域的合作研究项目。法国项目负责人是Jean-Loup Chenot博士。这项研究将侧重于比较和开发两个实验室创建的用于分析工业板材成形操作的现有有限元程序。纳入比较结果的改进方案预计将是这一合作的主要成果。将对基本公式、编程技术和数值实现进行比较和对比。具体地说，这些程序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“健壮性”)。每个标准的最佳技术将被确定和保留，以便为最终的工业使用构建更实用的方案。法国实验室的研究将专注于输入/输出密集型测试和开发，而美国的工作将侧重于大规模计算，以利用每个地点的特殊优势。
