Read or download book entitled Applications of ATILA FEM Software to Smart Materials written by Kenji Uchino which was release on 27 November 2012, this book published by Elsevier. Available in PDF, EPUB and Kindle Format. Book excerpt: 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.

Summary : Finite element analysis can be applied to smart structures with piezoelectric or magnetostrictive materials rather successfully when neither the applying electric field nor the generating AC strain is very large and when the linear relation can be supposed in the strain vs electric field or the strain vs stress. However, ...

Summary : 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 ...

Summary : The damping of a structure can be obtained by a transfer of the vibratory energy into thermal energy (dissipation in an electrical resistance). The transfer is carried out by using piezoelectric materials (PZT piezoelectric plate) and is improved by charging the piezoelectric material by an electrical circuit. This chapter describes ...

Summary : Piezoelectric ultrasonic motors offer many advantages such as high retention being very controllable, high torque at low speed, light weight, simple structure and no electromagnetic field induction compared with the conventional electromagnetic motors. These advantages have helped to expand the application fields where precise position control and rotational/linear motions ...

Summary : In this chapter, a coupled electromechanical thermal analysis is presented. For a steady-state solution, the thermal behaviour is weakly coupled to the electromechanical response. A simple model, a tonpilz, a doubled-ended and a flextensional transducer serve as validation of the numerical model compared to the analytical models. The transient thermal ...

Summary : Traditional transmitting materials, such as PZT-8, exhibit some non-linearity in stress and temperature, but predicting performance under high stress and higher temperatures can be achieved by taking advantage of the weak coupling. One needs to predict the performance of these devices by considering the highly non-linear behaviour with a fully ...

Summary : 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 ...

Summary : The vibration and sound radiation of structures, like plates or shells stiffened by frames or ribs, is a problem of interest in the analysis of aircraft and marine structures. If the ribs are uniformly spaced, then the composite structure is spatially periodic. Many authors have proposed solutions for stiffened infinite ...

Summary : 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 ...

Summary : This chapter provides the utilization of piezoelectric polarization. In smart structures, the polarization and the electric field are not necessarily parallel to each other. However, applying an electric field in a particular direction may change the behaviour of the device. Sections 5.3 to 5.5 present the utilization of Cartesian polarization with different ...
