SONAR transducer analysis using a coupled FE-BE method

결합형 유한요소-경계요소 기법을 사용한 쏘나 트랜스듀서의 분석

This paper describes how the directivity pattern of the back-scattered sound pressure is distributed when a plane acoustic wave is incident on a righid spherical shell underwater. A coupled Finite Element-Boundary Element mehtod is developed as numerical technique. The result of the coupled FE-BE method is agreed with theoretical solution for algorithmic confirmation.
