Acoustic bulletin, Vol. 14 ¹ 3, (2011) |
| The paper deals with solving of a problem on SH wave diffraction by the interface crack in a junction of an elastic plate and a half-space. By the Wiener-Hopf technique, the problem is reduced to solving of the infinite system of linear algebraic equations. The eigenvalues of an operator of the dynamic problem that determines the complex resonant frequencies are studied. The examples of dependencies of eigen frequencies and vibration modes from the parameters of structure are presented. |
