“…Nonlinear analysis methods focusing on nonclassical nonlinear behavior of interfaces are referred to as local nonlinearities, which have attracted increasing interest in theoretical and applied research in the past few years. 26,27 Kim et al 28 developed a nonlinear model for investigating the contact acoustic nonlinearity (CAN) of a closed crack in aluminum plate in order to analyze the nonlinear characteristics of the transmitted waves. These studies have found that the interfacial stiffness has a significant effect on the amplitude of the resultant second-order harmonic.…”

“…actuator induced elastic wave propagation in the sample SCS (450 mm × 450 mm × 2 mm) is carried out using the explicit and implicit solvers in ABAQUS [38]. In the process, the explicit analysis code was used for modeling of the SCS and the implicit analysis code was used to model the PZTs [2].…”

“…Recent studies have primarily focused on the investigation of higher harmonic generation due to the J o u r n a l P r e -p r o o f presence of nonlinear-elasticity [28,35] and contact-nonlinearity [36][37] phenomena. A contact acoustic nonlinearity model of a closed crack in an aluminium plate was developed for the analysis of nonlinear characteristics of the crack induced elastic waves in the structure [38]. The results showed that the interfacial-stiffness significantly affects the amplitude of the secondorder harmonics in frequency-domain signals, and the second harmonic amplitudes correlate with the crack-closure process.…”

“…is provides the possibility of damage detection for the contact interfaces. In subsequent studies, the HHG technique for contact interface detection has been extensively studied [17][18][19], and the nonlinear parameter β is generally used to characterize the damage. However, there are still many barriers before applying this technique in practical test.…”

Second harmonic generation (SHG) is one of the common techniques in the nonlinear ultrasonic test. The contact-type defects play an important role in material damage, which are hard to be detected. The traditional nonlinear parameter β used to evaluate the micro damage in material is derived from the classical stress-strain relation, which is more suitable for the anharmonicity of crystal rather than the contact-type defects. Recently, the theoretical model based on the bilinear stiffness law was derived, and the validity and applicability need to be further studied. For this purpose, by the numerical method, the contact interface in mortar is characterized based on the damage indicator γ. The relation between the excitation voltage and γ is obtained. Moreover, the effects of the crack length and orientation on the damage indicator γ are also obtained. The experimental method is also used to characterize the contact interface in mortar. Combining with the existing work, the results obtained in this article are discussed, and further conclusions can be drawn. The conclusions in this article provide potential of quantitative detection of the contact interface and quality evaluation of bonding layers in materials.
