Acoustic bulletin, Vol. 15 ¹ 1, (2012) |
| A scattering of the Rayleigh-Lamb waves on a vertical crack in an elastic waveguide is calculated by a method of superposition. A good convergence of solution is provided by the allowance for singularity on stresses arising at the angular point of the crack. The numerical results confirming the efficiency of the method are presented. |
