On the basis of a numerical analysis, a boundary resonance in a semi- infinite elastic waveguide with mixed boundary conditions, when a part of the surface is rigidly fixed while a force which is harmonically dependent on time is imposed on the other part, is found and analysed. The specific behaviour of the amplitude of excitation of a normal wave with a purely imaginary propagation constant in the neighbourhood of the frequency of the boundary resonance is found.
