| Abstract: | The problem of a symmetric wave impact on the Euler beam is solved by the normal modes method. The liquid is supposed to be
ideal and incompressible. The initial stage of impact when hydrodynamic loads are very high and the beam is wetted only partially
is considered. The flow of a liquid and the size of the wetted part of the body are determined by the Wagner approach with
a simultaneous calculation of the beam deflection. The specific features of the developed numerical algorithm are demonstrated
and the criterion of its stability is specified. In addition to a direct solution of the problem, two approximate approaches
within the framework of which the dimension of the contact region is found ignoring the deformations of the plate are considered.
