Paper Abstract

A new element is developed for the analysis of laminated/sandwich beams incorporating piezoelectric layers. Beam theory employed here satisfies the interface stress and displacement continuity and has zero shear stress on the top and bottom surfaces of the beam. Piezoelectric layers can be placed arbitrarily and can act as sensors and actuators. The transverse shear deformation in the form of trigonometric sine function is incorporated to define the transverse shear strain. The displacement and stress variations along the length and thickness obtained are presented.
