Theoretical aspects of applying love and SH-waves to nondestructive testing of stratified media

Research into applications of acoustic SH-waves and Love waves to nondestructive testing of stratified media is reviewed. A mathematical model has been developed for describing the propagation of waves with horizontal polarization (SH-waves and Love waves) in anisotropic (monoclinic) stratified media. A modified transfer-matrix method (TM-method) has been developed in order to obtain the solution. Noncanonical-type waves with horizontal transverse polarization have been studied. The dispersion curves have been obtained for a multilayer composite that is in contact with an anisotropic semi-infinite space. It has been shown that the physical characteristics and geometry of any internal layer can be determined based on changes in the dispersion curves.
