TLDR
In this paper, a comprehensive analysis as to which wave modes have the capability to generate cumulative second harmonic guided waves is presented, and an approach to predict the nature of higher harmonics is presented.Abstract:
Use of nonlinear guided waves appears to be a promising option for material characterization, but appropriate guided wave mode selection is a critical issue. To that end, an outline of a comprehensive analysis as to which guided wave modes have the capability to generate cumulative second harmonic guided waves is presented. The problem of higher harmonic guided wave generation in plates is studied and an approach to predict the nature of higher harmonics is presented.read more
