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.

A focus of the workshop was on fatigue behavior and estimation of time or cycles to failure, including a new generation of fatigue resistant materials. Contributions were on both fundamental and applied levels with highest priority assigned to revolutionary experimental and simulation approaches to support the materials genome initiative. The outcomes include the Workshop held in Changwon, Korea titled "Fatigue, Fracture and Reliability of Aging Structures" held on June 14, 2014. The workshop included 16 presentations that were discussed in detail. The Workshop was attended by a geographically diverse group of participants from Germany, India, South Korea, France, the United Kingdom, the People’s Republic of China, and the United States of America. The participants and presenters had diverse backgrounds including National Laboratories, consulting organizations, and Universities. The integration across the broad areas of investigation ranged from the simulation of dislocation dynamics to statistical parsing of natural language abstracting code for fatigue failure event databases. Each of the presentations was followed by a discussion period with a discussion moderator for each topic presented. The Workshop advanced discovery and understanding across multiple scales while promoting learning and teaching through the University participants who incorporated the material into their ongoing future research endeavors. Collaborations were formed both at the Workshop and thereafter. Results were disseminated through resulting journal article submissions. The benefits to society include fostering of a better understanding of the structural aging of critical systems and how best to design and monitor such systems to insure safe and efficient operation of such systems. This understanding was made possible through the diverse geographic and technical backgrounds of the Workshop participants. Additionally, conference papers and journal manuscripts were submitted based on this Workshop and are now in review or revision.
