This book provides the critical knowledge and technological bases required for meeting one of the ultimate engineering challenges: the design and construction of smart structures and systems. Research in smart materials and structures seeks to apply multifunctional capabilities of new and existing materials to develop structures and systems that are capable of self-sensing and monitoring, self-diagnosis and prognosis with intelligence, self-healing and repair, and adaptive response to prevent loss of human life and catastrophe, to minimize maintenance and life-cycle costs, and to prolong service life. The papers contained herein, representing the state-of-the-art in the field, were presented at the World Forum on Smart Materials and Smart Structures Technology (SMSS) held in Chongqing and Nanjing, China on May 22-27, 2007.
