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

该奖项将支持俄亥俄州立大学Robert Wagoner博士与巴黎国立高等矿业学院材料成型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。该研究将集中于比较和开发两个实验室创建的现有有限元程序，以分析工业板材成形操作。纳入比较结果的改进方案预计将是这一合作的主要成果。基本公式，编程技术和数值实现将进行比较和对比。具体来说，这些程序将在三个主要方面进行比较：准确性、计算时间效率和稳定性（或“鲁棒性”）。将确定并保留每个标准的最佳技术，以便为最终的工业应用构建更实际的程序。法国实验室的研究将侧重于输入/输出密集型测试和开发，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.
