Paper Abstract

The electrical and mechanical field distributions inside the layers of a piezolaminate beam are calculated when excited by a harmonic load or electric potential applied on the surface of the laminate. The Fourier series solution approach is used to solve the electroelasticity problem and the electrical and mechanical field distributions are estimated at frequencies away and close to the natural frequency of the laminate. Numerical results are computed for a single piezoelectric layer and a three layered piezoelectric laminate under cylindrical bending vibration. Our results indicate that the approximations made in many papers dealing with laminated piezoelectric beams are unjustified especially close to structural resonance frequencies at which control of vibration is most often desired.
