Applications of ATILA FEM Software to Smart Materials
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. - Provides an indispensable guide to the use of ATILA FEM software in the design of effective products - Discusses new capabilities and loss integration of the software code, before presenting case studies of finite element modelling using ATILA - Discusses the behaviour of piezoelectric single crystals for sonar and thermal analysis in piezoelectric and magnetostrictive materials, before a reflection on the use of ATILA in modelling the damping of piezoelectric structures
Applications of ATILA FEM software to smart materials
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.
Applications of ATILA FEM software to smart materials
This chapter describes time domain analysis capabilities of ATILA which might be useful in evaluating acoustic wave propagation and reflection by transducers, transient signal response of sensors, and overshoot and ringing behaviors for actuators. Three examples from different application fields were selected to show how time domain analysis can be achieved in ATILA, focusing on an analytical approach in simulation modeling, decisions based on transient module parameters, and interpretation of time domain results.
