Observance of Stoneley waves at the Lamb wave dispersion in stratified media

摘要

Observance of Stoneley waves at the guided wave dispersion in stratified plates containing layers with alternating contrast physical properties is analyzed by applying Cauchy sextic formalism coupled with the exponential fundamental matrix method. Additional high-frequency asymptotes related to appearing interfacial Stoneley waves are detected and analyzed. Comparison with the case when Stoneley waves do not exist is presented.
