Sandwich plates are certain specific type of composites, which are widely used in modern engineering. Due to their complicated multi-layered structure, in literature one can find many different modelling approaches: from a simple double-plate system to a complex theories based on complicated deformation hypothesis. In this paper the modelling of vibrations of sandwich plates is considered, as a brief resume of assumptions of several models along with their governing equations of motion are presented. In the calculation example the free vibrations of a certain sandwich plate strip are investigated with the use of all described models and additionally with the use of FEM model. Eventually, basing on the presented comparison of the obtained results, the discussion on the correctness of each modelling assumption is made.
