摘要: Deals with the development and evaluation of finite element models for monolithic array elements manufactured from 1-3 piezocomposite materials. The approach is verified by comparing results example analyses experimental measurements. are then used to predict influence varying different parameters transducer construction on behaviour an individual element. This includes changing aspect ratio ceramic pillars number under active electrode pattern. were also extended incorporate matching layers, backing blocks load media performance device. From this extensive set simulations, a design guidelines derived presented ultrasonic arrays.
