An exact local model for computing the coincidence frequencies of multilayered sandwich panels and numerical results predicted by the model are presented in the paper. The model is derived within the local theory of linear elastodynamics without any simplifications concerning the structure. The coincidence frequencies for homogeneous panels and for five-layer and seven-layer sandwich panels are obtained and compared with corresponding results predicted by the models existing in the literature. Both flexural and breathing waves propagating in the sandwich structures are considered.
