本文目的為探討具有貼附式壓電材料之複合材料曲樑的結構特性；此結構上層與下層為壓電材料薄片，中間層為堆疊六層之複合材料，總合構成一曲樑。
為了瞭解曲樑之力學行為，利用應力場、應變場、連續位移條件與溫度分佈公式的關係推導出應變能和動能公式，再以Hamilton’s Principle求得運動方程式和邊界條件。
利用靜態結構方程式推導出位移場通解，並個別帶入邊界條件可以後獲得其位移場特解。
在探討在不同的纖維角度的複合材與施與不同負載如:集中外力、溫差與電位差可以求的曲樑的應力與應變的分布情形，進而加以比較分析。

A curved composited beam partially surface-mounted with piezoelectric material is considered in this paper. The curved beam element is based on Timoshenko beam theory.The mathematical model is based on a continuous displacement conditions piezoelectric field and temperature distribution formula. Then the strain energy and kinetic energy derived by the stress and the strain.Governing equation and boundary conditions are derived by Hamilton’s Principle.
General solution of displacement field equations derived from the static structure. General solution can obtain special solutions constant by different boundary conditions.In the role of external force, temperature and potential difference,Stress and strain distribution can be obtained.
