Monolithic piezoelectric ceramic devices are well understood and employed in a wide variety of structural actuation and sensing applications. Over the last twenty years piezoceramic fiber composites with interdigitated electrodes (IDE) have fallen into favor. These piezocomposite devices with IDE have been shown to be more conformal, durable and responsive than conventional monolithic devices. One of the more prevalent piezocomposite devices with IDE is the Macro Fiber Composite (MFC) developed at the NASA-Langley Research Center. The MFC shows superior free strain actuation performance, manufacturability and reliability over conventional devices. While the MFC boasts some improved characteristics over conventional devices, the use of IDE also introduces added complexity. Simple in design, the IDE causes nonuniform electric fields, large electric field gradients and increased hysteresis in the device. Characterization and modeling efforts of the MFC beyond a linear approximation have been limited. The majority of published work relies on experimental quantification and a heavy reliance on linear finite element analysis. The MFC has significant time dependent effects, conduction issues, creep, and other nonlinear effects that have not been explored. This study serves as an attempt to rectify some of the previously overlooked issues of non-linearity in piezocomposite actuators with IDE. As a baseline of comparison, the capability of a MFC to serve as a strain sensing/actuating rosette was compared to single crystal PMN-PT. It was found that increased hysteresis and creep caused the MFC to perform poorly by comparison. This spurred the process of seeking improved IDE designs. A twenty actuator study was performed using actuators with different electrode line widths and spacings. It was found that the hysteresis of an actuator with IDE could be reduced, but with the sacrifice of some of the free strain actuation. For accurate strain sensing/actuation, devices with large electrode line widths were found to show less hysteresis. For maximal free strain actuation, devices with small electrode line widths and large electrode spacing were found to have larger free strain actuation. The free strain frequency response was explored for the MFC, and custom devices were designed to mitigate some of the frequency dependence. The IDE devices were characterized using a dielectric finite element model and using a nonlinear ferroelectric finite element model. A phase field model was also developed to explore domain formation along electrode edges.

This book introduces physical effects and fundamentals of piezoelectric sensors and actuators. It gives a comprehensive overview of piezoelectric materials such as quartz crystals and polycrystalline ceramic materials. Different modeling approaches and methods to precisely predict the behavior of piezoelectric devices are described. Furthermore, a simulation-based approach is detailed which enables the reliable characterization of sensor and actuator materials. One focus of the book lies on piezoelectric ultrasonic transducers. An optical approach is presented that allows the quantitative determination of the resulting sound fields. The book also deals with various applications of piezoelectric sensors and actuators. In particular, the studied application areas are · process measurement technology, · ultrasonic imaging, · piezoelectric positioning systems and · piezoelectric motors. The book addresses students, academic as well as industrial reseachers and development engineers who are concerned with piezoelectric sensors and actuators.

Two key words for mechanical engineering in the future are Micro and Intelligence. It is weIl known that the leadership in the intelligence technology is a marter of vital importance for the future status of industrial society, and thus national research projects for intelligent materials, structures and machines have started not only in advanced countries, but also in developing countries. Materials and structures which have self-sensing, diagnosis and actuating systems, are called intelligent or smart, and are of growing research interest in the world. In this situation, the IUT AM symposium on Dynamics 0/ Advanced Materials and Smart Structures was a timely one. Smart materials and structures are those equipped with sensors and actuators to achieve their designed performance in achanging environment. They have complex structural properties and mechanical responses. Many engineering problems, such as interface and edge phenomena, mechanical and electro-magnetic interaction/coupling and sensing, actuating and control techniques, arise in the development ofintelligent structures. Due to the multi-disciplinary nature ofthese problems, all ofthe classical sciences and technologies, such as applied mathematics, material science, solid and fluid mechanics, control techniques and others must be assembled and used to solve them. IUTAM weIl understands the importance ofthis emerging technology. An IUTAM symposium on Smart Structures and Structronic Systems (Chaired by U.

This monograph presents new model-based design methods for trajectory planning, feedback stabilization, state estimation, and tracking control of distributed-parameter systems governed by partial differential equations (PDEs). Flatness and backstepping techniques and their generalization to PDEs with higher-dimensional spatial domain lie at the core of this treatise. This includes the development of systematic late lumping design procedures and the deduction of semi-numerical approaches using suitable approximation methods. Theoretical developments are combined with both simulation examples and experimental results to bridge the gap between mathematical theory and control engineering practice in the rapidly evolving PDE control area. The text is divided into five parts featuring: - a literature survey of paradigms and control design methods for PDE systems - the first principle mathematical modeling of applications arising in heat and mass transfer, interconnected multi-agent systems, and piezo-actuated smart elastic structures - the generalization of flatness-based trajectory planning and feedforward control to parabolic and biharmonic PDE systems defined on general higher-dimensional domains - an extension of the backstepping approach to the feedback control and observer design for parabolic PDEs with parallelepiped domain and spatially and time varying parameters - the development of design techniques to realize exponentially stabilizing tracking control - the evaluation in simulations and experiments Control of Higher-Dimensional PDEs — Flatness and Backstepping Designs is an advanced research monograph for graduate students in applied mathematics, control theory, and related fields. The book may serve as a reference to recent developments for researchers and control engineers interested in the analysis and control of systems governed by PDEs.

The increased level of activity on structural health monitoring (SHM) in various universities and research labs has resulted in the development of new methodologies for both identifying the existing damage in structures and predicting the onset of damage that may occur during service. Designers often have to consult a variety of textbooks, journal papers and reports, because many of these methodologies require advanced knowledge of mechanics, dynamics, wave propagation, and material science. Computational Techniques for Structural Health Monitoring gives a one-volume, in-depth introduction to the different computational methodologies available for rapid detection of flaws in structures. Techniques, algorithms and results are presented in a way that allows their direct application. A number of case studies are included to highlight further the practical aspects of the selected topics. Computational Techniques for Structural Health Monitoring also provides the reader with numerical simulation tools that are essential to the development of novel algorithms for the interpretation of experimental measurements, and for the identification of damage and its characterization. Upon reading Computational Techniques for Structural Health Monitoring, graduate students will be able to begin research-level work in the area of structural health monitoring. The level of detail in the description of formulation and implementation also allows engineers to apply the concepts directly in their research.
