This award provides funding for a workshop to be held May 31 thru June 3, 2010 in Jeju, Korea for leading US and Asian-Pacific science and engineering researchers to assess the current research status in the area of smart sensing and actuatiion, to identify future research topics and collaboration opportunities, and to provide input to US and Korean funding agencies on future research directions and effective funding mechanisms. The emergent research field of smart sensing and actuation has attracted significant attention in recent years. A delegation of 12 researchers from the US, representing a wide range of expertise from engineering to biology will participate in this important workshop.
The outcome of this workshop has the potential to produce future structures that are capable of self-sensing and monitoring, self-diagnosis and prognosis with intelligence, self-healing and repair, and adaptive response to prevent catastrophe, minimize maintenance, and prolong service life. A report that identifies the most promising plans of actions to advance in this area will be produced. Successful completion of this workshop will facilitate broader international collaboration, technology transfer of research data in smart sensing and actuation, especially in topics of multi-scale mechanics and multi-functional materials.
US-Korea Workshop on Multi-scale Mechanics and Multi-functional Materials for Smart Sensing and Actuation on May 31st – June 4th, 2010 in Jeju, South Korea Summary The US-Korea Workshop on Multi-scale Mechanics and Multi-functional Materials for Smart Sensing and Actuation was held in Jeju, South Korea on May 31 – June 4, 2010. The US delegation consists of 12 US scientist and engineer researchers across the United States. The Korean delegation consists of 23 Korean researchers from academia and industry in Korea. US and Korean researchers presented their research findings and addressed the critical issues faced by the research community in the field of multi-scale mechanics and multi-functional materials for smart sensing and actuation. The participants also formed two groups to discuss the challenges and future directions for research. The Workshop help promote bilateral collaborations between US and Korean researchers, and help provide guidance for future research directions. 1.

Working Group I Report on the Multi-Scale Mechanics and Multi-Functional Materials Challenges The linkage between multi-scale mechanics/multi-functional materials and sensing and actuation for the health of structures is clear. The damage that eventually compromises the performance of bridges, buildings, pipelines, wind energy structures and aerospace structures occurs at many scales, at multiple sites and in multiple forms and over long periods of time. Thus the purpose of this workshop has been to try to identify where the grand challenges lie for this area. Many of the developments may lie in the development of numerical models, but these must be properly informed by experiments of discovery, validated for consistency and then verified by well chosen experiments. Next Steps Multi-scale materials modeling/multifunctional materials and smart sensing/actuation are two exciting research fields. They also promise to revolutionize engineering practice in structural health monitoring and repair. However, the integration of research and fruitful collaboration between these two groups is rare. Establishment of one to two test beds in Korea and the US (in consultation with workshop group II) might serve to promote and facilitate such collaboration between US and Korean researchers. Associated test bed websites/blogs would allow groups to upload most recent publications, present state-of-the-art research and challenges, and encourage discussion and follow up. 3-2. Working Group II Report on the Multi-Scale Mechanics and Multi-Functional Materials Challenges Monitoring of interconnected multi-scale heterogonous infrastructure systems is very problem dependent, and it is data driven. It is also important to construct physics based models for SHM. Additional challenges are (a) how to achieve necessary spatial density of data, (b) how to transform data into decision making, (c) there should be much collaboration between experimentalist and theoretical physics, (d) how to extend SHM to structural prognosis, (e) uncertainty in a micro scale should be scaled up to a macro level, (f) there has been a large volume of research for constructing low-frequency and high-frequency modeling. But still there is more room for research in middle frequency range modeling.
