碩士 === 國立成功大學 === 工程科學系碩博士班 === 98 === 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 .
