Nanocomposites for Distributed Structural Monitoring and Damage Detection

Speaker: Dr. Kenneth J. Loh,
Assistant Professor, University of California, Davis, Department of Civil & Environmental Engineering, One Shields Avenue, 2001 Engineering III, Davis, CA 95616, USA Abstract: Structural deterioration, excessive loading, impact damage, and corrosion have been identified as critical and long-term problems that constantly threaten the integrity and reliability of structural systems (e.g., civil infrastructures, aircrafts, and naval vessels). In particular, the field of structural health monitoring (SHM) and damage detection provides quantitative global- and component-scale structural response data for monitoring the performance of these structures; however, most sensors are subjected to performance limitations (e.g., sensitivity, dynamic range, bandwidth, and form factor) and only offer measurement of structural behavior at discrete locations. In this regard, nanotechnology offers a plethora of nanomaterial fabrication techniques for the design of next-generation multifunctional nanostructured systems to solve complex engineering problems. Multifunctional systems are defined to possess a diverse suite of engineering functionalities including self-sensing, actuation, self-healing, power harvesting, among many others. Here, carbon nanotubes are employed and encoded with a variety of electrochemical and electromechanical sensing transduction mechanisms for structural health monitoring and damage identification. First, using a layer-by-layer nanocomposite assembly technique, the films' electrical properties change linearly in response to applied external stimuli (e.g., tensile-compressive cyclic loading and pH). When coupled with radio frequency identification (RFID) technologies, a low cost and high performance passive wireless sensor is fabricated for densely-distributed SHM. Laboratory validation studies demonstrate that these sensors can measure strain and pH/corrosion at its instrumented locations, but damage localization requires interpolation between sensors. Alternatively, the proposed carbon nanotube-based films are paired with an electrical impedance tomographic conductivity image reconstruction algorithm. Specifically, the nanocomposite "sensing skins" are validated for spatial strain, pH, corrosion, and impact damage sensing and is shown to be capable of accurately identifying damage (i.e., strain, impact, and corrosion) location and magnitude. Biography Dr. Kenneth J. Loh is an Assistant Professor in the Department of Civil & Environmental Engineering at the University of California, Davis. He received his B.S. degree in Civil Engineering from Johns Hopkins University in 2004. He continued his graduate studies at the University of Michigan where he completed his M.S. degree in Civil Engineering in 2005, a second M.S. degree in Materials Science & Engineering in 2008, and a Ph.D. degree in Civil Engineering in 2008. His research interests include the development of multifunctional nanocomposites, biologically-inspired materials for sensing, actuation, and power harvesting applications, and wireless sensing.

DANIEL J. EPSTEIN DEPARTMENT OF INDUSTRIAL AND SYSTEMS ENGINEERING SEMINARTitle: "Network Models and Optimization: Multiobjective Hybrid GA Approach"Guest Speaker: Mitsuo Gen, PhD, Fuzzy Logic Systems Institute, Iizuka, Japan, gen@flsi.or.jpDate/Time/Place: Thursday, November 5, 2009, 3:30–4:50 PM, Andrus Gerontology Building (GER) Room 309ABSTRACT: Network models provide a useful way for modeling various real world problems and are extensively used in many different types of systems: Mechanical, Electronic, Communications, Manufacturing and Logistics areas. Network design optimization is basically a fundamental issue in various fields, including Applied Mathematics, Computer Science, Engineering, Management, and Operations Research. Network models and design optimization for various Routing/Scheduling problems in Transportation, Communication, Manufacturing and Logistics systems also provide a useful way as one of case studies in real world problems and are extensively used in practice.
Genetic and Evolutionary Algorithms in AI (Artificial Intelligence) technique have recently received a considerable attention because of its potential of being a very effective design optimization technique for solving various NP hard problems and complex Information Processing, Manufacturing and Logistics systems.
The Tutorial introduces a thorough treatment of Multiobjective Hybrid Genetic Algorithms (moh-GA) to treat the following network optimization problems based on the book, M. Gen, R. Cheng & L. Lin: "Network Models and Optimization: Multiobjective Genetic Algorithm Approach", 710pp, Springer, London, 2008:Part 1. Shortest Path Routing ModelsPart 2. MST (Minimum Spanning Tree)-based Network ModelsPart 3. AGV (Automatic Guided Vehicle) Network Model in FMS BIO: Dr. Mitsuo Gen is a Visiting Scientist at Fuzzy Logic Systems Institute, Iizuka, Japan since Aug. 2009 and was a Visiting Prof. at Pohang University of Science & Technology (Sept. 2008 - Feb. 2009) and joined as a Professor at Graduate School of Information, Production and Systems, Waseda University, Japan since April 2003. He received a PhD in Engineering from Kogakuin University in 1974 and PhD in Informatics from Kyoto University in 2006. He was a Lecturer during 1974–1980, an Associate Professor during 1980–1987, a Professor during 1987–2003 at Ashikaga Institute of Technology. He was a Visiting Associate Professor at the University of Nebraska-Lincoln, USA in 1981–1982 and a Visiting Professor at University of California at Berkeley, USA from Aug. 1999 to March 2000. His research interests include Genetic & Evolutionary Algorithms, Artificial Neural Network, Fuzzy Logic & Systems and their applications to scheduling, network design, system reliability design, etc. He has authored several books, such as Genetic Algorithms and Engineering Design, John Wiley & Sons, New York (1997), Genetic Algorithms and Engineering Optimization, John Wiley & Sons, New York (2000) with Dr. R. Cheng and Network Models and Optimization: Multiobjective Genetic Algorithm Approach, Springer, London (2008) with Dr. R. Cheng and Dr. L. Lin, edited Intelligent and Evolutionary Systems, 240pp, Studies in Computational Intelligence, vol. 187, Springer-Verlag, Heidelberg (2009) by Dr. M.
