Reflection and transmission of sound waves through the interfacial boundary of two joined elastic half-strips

A numerical solution of the problem of the incidence of plane harmonic waves on the interfacial boundary of two joined half-strips with different elastic properties is presented. A detailed analysis is given of the reflection and transmission of the incident wave energy through the inter-facial boundary, and the nature of the state of stress and strain is investigated in its neighbourhood. The wave fields in longitudinally inhomogeneous media were studied earlier in /1–3/ etc.
