Presidential Young Investigators Awards

高性能计算对当代科学和工程问题的重要性已经得到了很好的证明。这位总统青年研究员的目标是开发用于大规模计算的高效算法，特别是，能够解决三维、非线性结构力学问题的多重网格法。其中一些问题包括具有材料和几何非线性的复杂结构的稳定性。这些计算工具将使工程师能够更好地理解模式相互作用和缺陷等现象的影响对结构屈曲的敏感性。将特别努力在粗粒度(Cray，Alliant)和细粒度(CM，HperCube)系统上实现这些算法。

The importance of high performance computing to contemporary issues in science and engineering has been well documented. It is the goal of this Presidential Young Investigator to develop efficient algorithms for large scale computing, in particular, multigrid methods capable of solving three dimensional, nonlinear structural mechanics problems. Some of these problems include stability of complex structures with both material and geometric nonlinearities. These computational tools will allow the engineers to better understand the influence by such phenomena as mode interaction and imperfection sensitivity on bucking of structures. Special effort will be made to implement these algorithms on both coarse-grain (CRAY, Alliant) and fine-grain (CM, HperCube) Systems.
