Abstract
Wave characteristics are investigated in piezoelectric-coupled laminated fiber-reinforced composite cylindrical shells by considering the transverse shear effects, rotary inertia, and different polarizations of the piezoelectricity for the first time. The novelty of this study is to present a complete mathematical model to evaluate wave behavior in a laminated fiber-reinforced composite cylindrical shell coupled by the piezoelectric layer with different polarizations and considering the transverse shear effects and rotary inertia. Dispersion solutions for different wave modes are obtained by solving an eigenvalue problem. The effects of the piezoelectricity and its polarization on the wave dispersion behavior in different composites are studied. For different piezoelectric poling directions, the influences of laminate stacking sequence and fiber orientation on dispersion curves are investigated. The results of this study can be used for solving a wave propagation problem in smart composite shell structures considering different piezoelectric effects for dynamic stability evaluation and health monitoring.
