Abstract
A rectangular plate is considered, in which two opposite edges are freely supported, while the other two are supported by elastic beams. In this paper, we prove the duality of the solution of the problem of finding the rigidities of elastic beams by all natural oscillation frequencies of a plate. It is also shown that if the rank of a certain matrix is equal to 9, then both solutions of the problem of finding the rigidities of elastic beams can be found from 9 natural frequencies.
