    Notes: Abstract The paper studies the effects of a rapidly changed temperature on the free vibrations of simply supported sandwich plates. It has been taken into account that the properties of the facings and of the core of the sandwich plate change with the temperature. The effects of geometrical nonlinearities on the behaviour of the plate have also been included. The damping is considered by modelling the viscoelastic core as a Voigt-Kelvin solid. A Runge-Kutta method is employed to solve the governing equations and obtain the numerical results. It was found that the rapid change of temperature strongly affects the amplitude and frequency of the vibrations.

    Notes: Abstract The nonlinear, forced, damped vibrations of simply-supported rectangular sandwich plates with a viscoelastic core are studied. The general, nonlinear dynamic equations of asymmetrical sandwich plates are derived using the virtual work principle. Damping is taken into account by modelling the viscoelastic core as a Voigt-Kelvin solid. The harmonic balance method is employed for solving the equations of motion. The influence of the thickness of the layers and material properties on the nonlinear response of the plates is studied.
