Electromechanical Finite Element Models for Ultrasound Transducer Analysis and Design

点击翻译按钮获取中文摘要

A comprehensive Finite Element based code will be developed for the simulation and design of piezoelectric transducers. The code will permit complete, three- dimensional, time-domain finite element modeling of waves in piezoelectric-elastic-acoustic media. An existing Weidlinger Associates Finite Element program provides the basic frame work. During Phase I, piezoelectric and acoustic-potential finite elements will be added to the base code resulting in a global two and three-dimensional simulation code to model ultrasound-type transducers.
