Peculiarities of Quasi_Longitudinal Elastic Wave Propagation through the Interface between Isotropic and Anisotropic Media:Theoretical and Experimental Study

Popis výsledku v původním jazyce

The peculiarities of elastic wave propagation in a bilayer medium are studied theoretically and experimentally. One (isotropic) layer was an acrylic glass plate, and the other (anisotropic) was a quartz single-crystal. In experiments, the elastic waves were generated by a piezoelectric transmitter and received by a piezoelectric transducer contacting the surface of the model medium. The propagation time of a quasi-longitudinal wave was determined using high-order statistics. In the general case, the incident elastic waves are split at the interface between the layers: beams undergo double reflection and triple refraction. The measured dependences of the propagation times of quasi-longitudinal split waves on the angles of refraction are in satisfactoryagreement with the calculated ones. The calculation was performed by solving the Christoffel equation with allowance for the boundary conditions.
