INFLUENCES OF THERMAL LOAD, ROTARY INERTIA AND NONLINEAR DEFORMATION ON WAVE PROPAGATION IN PIEZOELECTRIC LAMINATED CYLINDRICAL SHELLS

Wave propagation in piezoelectric laminated cylindrical shell is studied considering the effect of nonlinear deformation, thermal loads and rotary inertia. From Hamilton’s principle, wave propagation governing equations of piezoelectric laminated cylindrical shells are derived. Wave propagation characteristic curve are obtained by solving an eigenvalue problem. The effect of nonlinear deformations, rotary inertia and thermal loads on wave propagation characteristic in piezoelectric laminated cylindrical shells is discussed through numerical examples. To verify the method, the result considering the effect of linear deformation on wave propagation in piezoelectric laminated cylindrical shells is compared with those obtained with different analytical methods in other literature.
