RIMI: Analysis of Dynamic Stress Fields in Pavements and Transportation Infrastructure

拟议的研究将使用DYNA3D，这是一种用于固体和结构力学的非线性、显式、三维有限元计算机代码（Whirley, Hallquist, 1991）。该代码由能源部开发，并被与能源部相关的研究人员广泛使用，并被与能源部、国防部、交通部以及大多数国家实验室和其他研究机构相关的研究人员广泛使用。DYNA3D是一个公共领域的计算机代码，由劳伦斯利弗莫尔国家实验室免费提供给FAMU/FSU工程学院。一些车辆、路边安全结构以及路面特性的有限元模型及其模型将由联邦和州机构提供，作为一项技术转让工作。将成立三个小型研究小组，每个小组由一名首席研究员和一名研究生组成，并将开展三个研究项目。该研究计划要求为所有三个研究小组提供资金，并为所有研究人员共享的一个计算机工作站提供资金。拟议的研究活动对提高交通领域的知识具有重要意义。这将有利于联邦和州运输机构以及与运输相关的行业，并有可能确保未来的研究支持。＊＊＊

9550687 Wekezer The proposed study will use DYNA3D, a nonlinear, explicit, three dimensional finite element computer code for solid and structural mechanics (Whirley, Hallquist, 1991). The code was developed by the Department of Energy and is being widely used by researchers associated with the Department of Energy and is being widely used by researchers associated with the Department of Energy, the Department of Defense, the Department of Transportation, and most of national laboratories and other research agencies. DYNA3D is a public domain computer code and is being provided by Lawrence Livermore National Laboratory to the FAMU/FSU College of Engineering at no charge. Finite element models of some vehicles, roadside safety structures, as well as pavement properties and their models will be provided by federal and state agencies as a technology transfer effort. Three small research groups consisting of one principal investigator and one graduate student each will be formed and will work on three research projects. The research proposal asks for funding to support all three research groups and for funding of one computer work station to be shared by all investigators. The proposed research activity is significant to the advancement of knowledge in the area of transportation. It will be beneficial to federal and state transportation agencies and to transportation related industries and it has a potential for securing future research support. ***
