Finite Element Analysis of Smart Composite Plates Containing Piezoelectric Actuator

압전 작동기가 포함된 스마트 복합재 평판의 유한 요소 해석

Recently, distributed piezoelectric actuators have drawn attention due to their potential applicability within smart structures. Because they serve not only as active components but also passive components, it is difficult to estimate their characteristics accurately. In this study a finite element method based on layerwise theory has been formulated to analyze the characteristics of the distributed piezoelectric actuators. The present method has the capability to describe more refined strain distribution and more realistic boundary conditions.
