    • 本文目的為探討具有部分貼附式壓電材料之複合材料曲樑的結構特性;複合材料樑與上下層貼上壓電材料薄片,構成部份貼附式壓電材料複合曲樑。
    為了瞭解曲樑之力學行為,利用應力場、應變場、連續位移條件的關係推導出應變能公式,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,並代入不同的邊界條件可獲得其位移場特解。
    再施予不同附載之集中外力、電位差探討不同壓電片位置、壓電片長度與壓電片厚度對位移、應變及應力的影響。

    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. Then the strain energy and kinetic energy derived by the stress、strains and continuous displacement. Governing equations and boundary conditions are derived by Hamilton’s Principle.
    General solutions of displacement field equations derived from the static structure. The constant of integration can be obtained by different boundary conditions .
    The effects of location、length and thickness of the piezoelectric pair on deflection、strain-stress of the entire curved beam are investigated .
