Wave propagation characteristics in a piezoelectric coupled laminated composite cylindrical shell by considering transverse shear effects and rotary inertia

Wave behavior is investigated in a piezoelectric coupled laminated fiber-reinforced composite cylindrical shell by considering the transverse shear effects and rotary inertia. A mathematical model is presented for analysis of wave propagation in a laminated fiber-reinforced composite cylindrical shell coated with the piezoelectric layer. By solving an eigenvalue problem, dispersion characteristics for different wave modes are obtained. Piezoelectric effect on dispersion curve is investigated. The effects of material properties of host substrate shell, laminate stacking sequence, and fiber orientation on dispersion curve are examined as well. In addition, a comparison of dispersion solutions from different shell theories with different axial and circumferential wave numbers and piezoelectric layer thickness is provided to illustrate the transverse shear and rotary inertia effects on wave behavior of a laminated fiber-reinforced composite shell. The results of this paper can be used for studies on wave propagation in piezoelectric coupled laminated composite shell structures and in design of smart composite shell structures with the piezoelectric material for health monitoring and dynamic stability evaluation.
