Paper Abstract

The electrostatic field in a fiber-reinforced composite cylinder with a piezoceramic core is investigated by using analytical methods. General solutions for composite and piezoceramic cylinders are derived by using Fourier integral transforms. These general solutions are used to analyze the response of a cylinder to a band of radial pressure. Numerical solutions for displacements, electric field and interfacial stresses of a glass-epoxy cylinder with a core made out of piezoceramics PZT-4 or PZT-6B are presented. The numerical solutions confirms the complex nature of the coupled elastic and electric fields in the cylinder and its dependence on the material properties and the geometry of the composite system. The analytical solutions presented in this paper can be used to analyze a variety of stress analysis and micromechanics problems related to fiber-reinforced composite cylinders with embedded piezoceramic layers.
