Description
Summary:In this paper, piezoelectric laminated cylindrical shells with shear piezoelectric actuators are discussed. Each of the response quantities of every layer of the shell is expanded in a double Fourier series in the local surface coordinates. A state-space approach is used to generate a 8 first-order ordinary homogeneous differential equations with variable coefficients. The frobenius method is used to get the solutions. Numerical results show the effects of the thickness ratios on the response quantities for electric loadings. A comparison of stresses between shear actuators and extension actuators reveals that the longitudinal stresses within the shear actuators are significantly smaller than those in the extension actuators, which means using shear actuators is better to brittle piezoceramic materials. We present results for 3 layers cylindrical shell structures with each lamina made of either graphite-epoxy or PZT-5A.
