Abstract
Forced planar vibrations of a rectangular plate consisting of two rectangular subdomains are studied. The mechanical properties of the subdomains are essentially different. The boundary conditions for the subdomains may also be different. It is shown that the more the difference between the properties of the subdomains, the closer to a certain limit is the first resonance frequency of the plate. It is established that under certain boundary conditions, the displacements in each of the subdomains may have their own specific features
