Abstract
This paper aims to present an analytical model on the classical laminated plate theory for deflections of multi-layered circular annular piezoelectric actuator subject to applied voltage. Analytical equations are solved in closed form and are validated numerically via finite element analysis and experimentally via static deflection vibrometer. The analytical (numerical) results are found to be in good agreement with experimental work. In this study, geometric packaging parameters, such as laminate thickness, annular diameter in the multi-layered structure, and residual stresses on the transverse deflection are investigated.
