Nonlinear steady-state oscillations of an elastic plate floating on the surface of a liquid of finite depth

In addition to obtaining solutions by the perturbation method it is shown that in the case of nonlinear wave interaction given a certain relationship between the parameters of the interacting waves steady-state compound waves may exist.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 3, pp. 146–154, May–June, 1989.
