Diffraction of the Rayleigh-Lamb waves on vertical boundary of composite elastic waveguide

Acoustic bulletin, Vol. 3 1, (2000) p.23-35
On basis of method of superposition the diffraction of the Rayleigh-Lamb wave on a vertical boundary of the waveguide formed by a strong contact of two halfstrips is calculated for case of their identical heights, but different elastic properties. The efficiency of a method is ensured with the account of singularity on stresses, which arises in an angular point on line of contact at particular combination of the elastic properties of media. Numerical results confirming the efficiency of method are presented. The analysis of frequency dependence of stresses in a contact zone is carried out.
