“…Previous studies have characterized corrosion damage using A0 wave for plates surrounded by air [38][39][40] and QS wave for plates in contact with liquid [21,41]. For partially immersed plates, it is also possible to evaluate the defects by sending A0 waves on the dry section of the plate and measuring the QS wave signals on the immersed section.…”

“…Although leaky S0 wave has low attenuation, it is not sensitive enough to identify small and shallow corrosion damage in the early stage [43][44][45]. In contrast, the QS wave has the shortest wavelength at a given frequency and provides better sensitivity than the leaky S0 wave to shallow hidden corrosion pits in immersed plates [41].…”

Propagating guided waves in a homogeneous, isotropic, prestressed, hyperelastic plate show nonlinear characteristics that depend on the state of initial prestress. These nonlinear phenomena include higher harmonic generation, occurring when Lamb wave modes of different frequencies ($$\omega _a$$ ω a and $$\omega _b$$ ω b ) are allowed to mix within the material generating secondary waves at frequencies $$2\omega _a,2\omega _b\, \text {and}\,\omega _a\pm \omega _b$$ 2 ω a , 2 ω b and ω a ± ω b . Further, if prescribed internal-resonance conditions are satisfied, the amplitude of secondary waves increases in space, providing a response quantity which is dependent on prestress and easy to be observed. Using the finite element method, in this paper we investigate the time and space evolution of higher harmonics arising in one-way wave mixing. The influence of prestress on the response is elucidated, observing the nonlinear parameter $$\beta $$ β . It is further shown that the nonlinear ultrasonic technique called sideband peak count-index (SPC-I) can provide an effective monitoring tool for prestress.
