Career: A Computer Test-Bed for First-Principle Simulation of Blast-Resistant Structures

抗爆结构第一原理模拟计算机试验台打击恐怖主义和确保美国安全是国家的优先事项。本项目的主要目标是开发一套用于抗爆结构第一性原理模拟的计算机试验台，以提高该领域的教育水平。为了预测爆炸荷载作用下结构的多尺度破坏，计划根据所涉及的物理原理研究三种基本类型的控制微分方程之间的转换，并在影响域中发展一种移动离散化方法来离散不同的尺度。将实施一项与研究计划相结合的协调教育计划，以促进抗爆设计方面的本科生、研究生和继续教育，鼓励少数族裔学生参与科学和工程领域的高级主题，并提高公众对恐怖主义和威胁防范的意识。这一研究和教育项目是新成立的国家防爆设计中心的重要组成部分，该中心代表着政府、行业和学术界之间强有力的合作伙伴关系。

A Computer Test-Bed for First-Principle Simulation of Blast-Resistant StructuresCombating terrorism and assuring the security of the United States is a national priority. The main objective of this project is to develop a computer test-bed for first-principle simulation of blast-resistant structures, and to improve the education in this area. To predict multi-scale structural failure under blast loads, it is planned that the transition among three basic types of governing differential equations be investigated based on the physics involved, and a moving discretization method in the domain of influence be developed to discretize different scales. A coordinated educational program, integrated with the research program, is to be performed to promote undergraduate, graduate and continuing education in blast-resistant design, to encourage minority students to get involved into advanced topics in science and engineering, and to improve the public awareness of terrorism and threat prevention. This research and educational program is an important part of the newly established National Center for Explosion Resistant Design that represents a strong partnership among government, industry and academia.
