This proposal seeks to make two advances in the dynamics of elasto- plastic structural mechanics: (1) to extend new methods of nonlinear dynamics and chaos to the fields of inelastic structural mechanics, especially using new experimental techniques such as Poincare maps and fractal mathematics, as well as explore spatial- temporal chaos in some applications of solid mechanics. (2) To develop radically new computational tools for analysis of nonlinear vibrations by inventing a way to put the computation on a chip using nonlinear cellular networks, as well as using both existing supercomputers.

这一建议旨在使弹性动力学的两个进步- 塑性结构力学：（1）推广新的方法， 非线性动力学和混沌理论应用于非弹性结构领域 力学，特别是使用新的实验技术，如 庞加莱地图和分形数学，以及探索空间- 固体力学中的时间混沌 (2)到 开发全新的计算工具，用于分析非线性 通过发明一种将计算放在芯片上的方法， 使用非线性蜂窝网络，以及使用现有的 超级计算机
