Book Description :

ATILA Finite Element Method (FEM) software facilitates the modelling and analysis of applications using piezoelectric, magnetostrictor and shape memory materials. It allows entire designs to be constructed, refined and optimized before production begins. Through a range of instructive case studies, Applications of ATILA FEM software to smart materials provides an indispensable guide to the use of this software in the design of effective products. Part one provides an introduction to ATILA FEM software, beginning with an overview of the software code. New capabilities and loss integration are discussed, before part two goes on to present case studies of finite element modelling using ATILA. The use of ATILA in finite element analysis, piezoelectric polarization, time domain analysis of piezoelectric devices and the design of ultrasonic motors is considered, before piezo-composite and photonic crystal applications are reviewed. The behaviour of piezoelectric single crystals for sonar and thermal analysis in piezoelectric and magnetostrictive materials is also discussed, before a final reflection on the use of ATILA in modelling the damping of piezoelectric structures and the behaviour of single crystal devices. With its distinguished editors and international team of expert contributors, Applications of ATILA FEM software to smart materials is a key reference work for all those involved in the research, design, development and application of smart materials, including electrical and mechanical engineers, academics and scientists working in piezoelectrics, magenetostrictors and shape memory materials.

Book Description :

For underwater applications and manufacture of sonar for autonomous underwater vehicles (AUV), large areas of piezoelectric materials with very good electromechanical properties are often needed. Piezoelectric single crystals (typically the compositions PMN-PT or PZN-PT) are high-performance materials (high yields), but are difficult to manufacture in large areas while maintaining homogeneous properties. This study on the behavior of piezoelectric single crystals will be conducted with the use of a finite-element code (ATILA) which was developed at ISEN in collaboration with the French Ministry of Defense. The results confirm the good fit between the models and experimental results after a phase of optimization.

Book Description :

The finite element method and its application to smart transducer systems are introduced in this chapter. The fundamentals of finite element analysis are introduced first. Then, the section ‘Defining the equations for the problem’ treats how to integrate the piezoelectric constitutive equations, and ‘Application of the finite element method’ describes the meshing. The last section ‘FEM simulation examples’ introduces six cases; multilayer actuator, Π-type linear ultrasonic motor, windmill ultrasonic motor, metal tube ultrasonic motor, piezoelectric transformer, and ‘cymbal’ underwater transducer, which includes most of the basic capabilities of ATILA FEM code.

Book Description :

Periodic structures have attracted considerable interest over the past three decades. Thus, passive structures with 1D or 2D periodicity are in standard use in underwater acoustics. Moreover doubly periodic active structures, such as 1–3 piezocomposite materials made of parallel piezoelectric bars embedded in a passive matrix, are also of great interest for mine hunting, underwater or medical ultrasonic imaging. In this chapter, a brief presentation of passive and active periodic structures is described. Then, the generic model developed for periodic studies is presented for the particular case of a 1–3 piezocomposite. The periodic structure is immersed in a fluid and the transmission and reflection coefficients are calculated. The test example discussed at the end of the chapter is devoted to an actual Alberich coating and an actual 1–3 piezocomposite for which previous experimental results are available.

Book Description :

Phononic crystals (PCs) are usually defined as artificial materials made of periodic arrangement of scatterers embedded in a matrix. The band structure of PCs may present under certain conditions absolute band gaps: they display frequency ranges in which waves cannot propagate. This fact is analogous to photonic band gaps for electromagnetic waves. Therefore, such systems can be applied as noise and vibration isolation, acoustic wave guiding, acoustic filters, etc. Moreover, band structures of PCs may exhibit dispersion curves with a negative slope, inducing negative refraction phenomenon. In this chapter, the general formalism is first presented. It is applied in the second part to a phononic crystal inducing filtering application and in the last section, negative refraction of elastic waves is presented for focusing application.

Book Description :

Students preparing to work with mechatronics, particularly with highly precise and smart actuators, face the challenge of designing and analyzing devices without formal and practical guidance in computer techniques. Finally there is a textbook that is as practical as it is authoritative: Kenji Uchino's FEM and Micromechatronics with ATILA Software. Ideal for Today's Computer-Based Curricula Every aspect of this book reflects its focus on being easy to use, easy to teach from, and above all, easy to implement. The first half of the text outlines the theory needed to develop and design smart actuators and transducers, while the second half walks students step-by-step through the software implementation using seven extensive examples. Even the book's lay-flat binding makes it easy for students to follow the text while working simultaneously at a computer. The companion CD-ROM supplies a free educational version of ATILA-Light. Unified Coverage for Integrated Technologies Covering the myriad challenges posed by smart transducers, the author introduces the fundamentals of piezoelectric and magnetostrictive devices, practical materials, device designs, drive and control techniques, and typical applications. Numerous problems and examples give students ample opportunity to put the concepts into practice. Outlining a complete treatment in 30 convenient 75 minute lessons, FEM and Micromechatronics with ATILA Software is a unique classroom text that students will continue to use throughout their entire careers.

Book Description :

Updating its bestselling predecessor, Ferroelectric Devices, Second Edition assesses the last decade of developments—and setbacks—in the commercialization of ferroelectricity. Field pioneer and esteemed author Uchino provides insight into why this relatively nascent and interdisciplinary process has failed so far without a systematic accumulation of fundamental knowledge regarding materials and device development. Filling the informational void, this collection of information reviews state-of-the-art research and development trends reflecting nano and optical technologies, environmental regulation, and alternative energy sources. Like the first edition, which became a standard in the field, this volume provides a general introduction to ferroelectrics with theoretical background. It then addresses practical design and device manufacturing, including recently developed processes and applications. Updating old data with a forecast of future developments, the text analyzes improvements to original ferroelectric devices to aid the design process of new ones. The second edition includes new sections on: Pb-free piezoelectrics Size effect on ferroelectricity Electrocaloric devices Micro mass sensor Piezoelectric energy harvesting Light valves and scanners Multi-ferroic devices, including magneto-electric sensors Uchino provides a general introduction to the theoretical background of ferroelectric devices, practical materials, device designs, drive/control techniques, and typical applications. He presents frequently asked questions from students, lab demonstrations for practical understanding, and "check point" quizzes and model solutions to monitor understanding. After a thorough exploration of ferroelectric devices and their past, this book looks to the industry’s future, assessing market size and remaining reliability/lifetime issues. The author also unveils his strategy for developing "best-selling" ferroelectric devices.
