The management of aging infrastructure such as bridges, dams, aircraft, nuclear reactors, oil and gas pipelines, and other complex systems has come into question. Hurricane Katrina; the Interstate 35 bridge collapse in Minneapolis, Minnesota and the Mianus River Bridge collapse in Connecticut; and the disaster at the Fukushima Daiichi nuclear power plant serve as recent notable examples. Due to the status of South Korea as an emerging international leader in advanced technology and manufacturing, an international workshop will be held in Changwon with a follow on visit to the Korean Advanced Institute of Science and Technology. International researchers from Germany, India, South Korea, France, the United Kingdom, the People's Republic of China, and the United States of America will exchange ideas for improved approaches related to the management of aging and high risk complex systems. Improved management of such systems will benefit the U.S. economy and society. A bound volume will summarize the workshop and provide recommendations for the future. In the post-Fukushima era, engineers are faced with increasing responsibility to come up with new and more effective tools for test data collection and mining, microstructural imaging, damage diagnostics, life-to-failure modeling, and cost-benefit risk-balanced analysis for time-critical decision-making to ensure the safety of the public. This workshop will address the knowledge gaps in the physics based prediction of service life and the benefits to be offered by rapidly evolving nondestructive evaluation and structural monitoring systems. A focus of the workshop is on fatigue behavior and estimation of time or cycles to failure, including a new generation of fatigue resistant materials. Contributions will be on a fundamental level with high priority assigned to revolutionary experimental and simulation approaches to support the materials genome initiative.

桥梁、水坝、飞机、核反应堆、石油和天然气管道以及其他复杂系统等老化基础设施的管理已经受到质疑。卡特里娜飓风;明尼苏达州明尼阿波利斯市35号州际公路大桥倒塌和康涅狄格州米纳斯河大桥倒塌;以及福岛第一核电站的灾难是最近的显著例子。鉴于韩国作为先进技术和制造业的新兴国际领导者的地位，将在昌原举行一次国际研讨会，并随后访问韩国先进科学技术研究院。来自德国、印度、韩国、法国、英国、中华人民共和国和美利坚合众国的国际研究人员将就与老龄化和高风险复杂系统管理相关的改进方法交换意见。改善这些系统的管理将有利于美国的经济和社会。一本合订本将总结研讨会的情况，并为今后提出建议。 在后福岛时代，工程师们面临着越来越多的责任，提出新的和更有效的工具，用于测试数据收集和挖掘，微观结构成像，损伤诊断，寿命故障建模和成本效益风险平衡分析，以确保公众的安全。本次研讨会将解决基于物理学的使用寿命预测的知识差距，以及快速发展的无损评估和结构监测系统所带来的好处。研讨会的重点是疲劳行为和估计的时间或周期失败，包括新一代的抗疲劳材料。贡献将是在一个基本的高度优先级分配给革命性的实验和模拟方法，以支持材料基因组计划。
