Acoustic bulletin, Vol. 9 ¹ 4, (2006) |
| The paper deals with solving of the plane problems of diffraction of elastic harmonic waves on periodic systems of cavities or rigid inclusions. By means of developed integral representations for displacement amplitudes of the reflected field, the boundary problems are reduced to the systems of singular integral equations that are solved numerically. The stress-strain state of the medium near the boundary of the cylinders is analyzed depending on the mechanical, dynamic and geometrical characteristics. |
