Peculiarities of normal wave excitation at bending vibration of a half-layer

Acoustic bulletin, Vol. 10 3, (2007) p.42-54
The paper deals with analyzing the features of the input energy distribution among different propagating modes in the elastic semi-layer at its antisymmetric vibration. Both the forced oscillation, and reflection of the first and second waves from the free end are considered. The significant frequency dependence of the energy transferred by a certain propagating wave is shown. Power consumption of the particular mode depends on frequency and type of loading.
KEY WORDS:
