A two-layer (metal–piezoceramic) beam with hinged ends under a nonstationary distributed load is considered. A method for solving the problem of active damping of the nonstationary flexural vibrations of this structure is proposed. The shape of the electric signal applied to the electrode of the electroelastic layer to keep the beam almost undeformed is identified. The solution is obtained using the Laplace transform with respect to time. Numerical results are presented and analyzed
