Abstract

Recent research uses second harmonic waves caused by material nonlinearity to characterize fatigue damage in its early stages. This research investigates this second harmonic Lamb wave generation analytically, using a solution derived by De Lima, in order to provide information on the efficient generation and detection of a second harmonic amplitude for improved signal-to-noise ratio in measurements. Symmetry properties of the second harmonic wave are also clarified, since the published literature is contradictory.
