N.S.Gorodetskaya, E.A.Nedil'ko Effect of mechanical characteristics of the contact media on interface reflecting properties in a composite elastic waveguide |
Acoustic bulletin, Vol. 15 ¹ 4, (2012) |
| On the basis of a superposition method, diffraction of antisymmetric Rayleigh-Lamb waves on a vertical boundary of a waveguide formed by a rigid contact of two halfstrips with equal heights, but different elastic properties is calculated. The efficiency of the method is provided by accounting for stress singularity occurring in the edge of a contact line at particular combinations of elastic properties of media. The analysis of energy transformation of the incidence wave into the reflected and transmitted ones is carried out. |
