Bending Deformation Increase of Bending-Extension Coupled Composite Beams Bonded with Actuator(s)

Abstract

This paper presents the results of three closely related studies on the bending deformation increase of beams made of bending-extension (be) coupled fiber-reinforced composites, such as N-layered regular (equal thickness layers) antisymmetric cross-ply laminates. The load ngs on the beams are either pure bending (without any strain actuation) or strain actuation induced by the actuators (such as lead zirconium titanate P%% drivers) bonded to both or one side of the beam. These represent the simplest loadings experienced by the low-frequency wall-driven projectors, consisting of surface-bonded PZT actuators and radiators made of ceramics, me aI% or recently fiber-reinforced com posites. The three studies have a direct bearing on developing composite bender bar projectors.
