Based on a Vlasov-type linear hypothesis, dynamic beam mass and stiffness coefficients, which account for both cross-section geometry and material anisotropy of the section, are analytically derived. The eigen-frequency problem is solved by Ritz energy method, and both exact transcendental and polynomial shape functions satisfying the boundary conditions of cantilever beams are used to describe the modal shapes. Piezoelectric ceramic (Lead zirconate titanate (PZT)) patches are used as smart sensors and surface-bonded near the cantilevered end of the I-beam. Vibration signals are measured by the PZT sensors, and the natural frequencies of the first three modes are obtained from the Power Spectral Density (PSD) plots. A good agreement of natural frequencies among the proposed analytical method, finite element analysis and smart experimental sensing is achieved. The proposed analytical solution and experimental testing using smart sensors can be used to effectively characterize the vibration behavior for FRP composite beams.
