Piezoelectric effects inducing flexural vibrations in viscoelastic sandwich panels are studied. Geometrically linearized conditions are considered, and the Bernoulli-Euler hypothesis is applied separately to each of the three layers. At the interfaces a linear viscoelastic slip law is assigned and a sixth-order initial-boundary value problem of the flexural vibrations is derived. In a numerical study, the frequency response function for the deflection of sandwich panels due to imposed time-harmonic piezoelectric eigenstrains is determined, which represents the important input function for computational methods in the frequency domain.
