“…However, it has been proved that the nonlinear techniques such as signal modulation [1], shift of resonance frequency [2] (e.g. nonlinear resonant ultrasound spectroscopy), sub-and higher harmonic generation [3], frequency mixing [4], modulation transfer (Luxembourg-Gorky effect) [5] and many others [6] are sensitive enough to observe any changes in structural integrity. As in the case of the whole monitoring system, the structure itself can exhibit multiple nonlinear sources, such as the material nonlinearity (usually exhibited through plasticity changes or thermal aging) [7], the cumulative presence of pores in freshly manufactured materials [8], delamination, de-bonding among the layers of the structure [8], the adhesive layer or debonding between the structure and transducer [9], and finally, the nonlinear movement of the cracks surfaces (breathing [10], micro-slip [11] or stick-and-slip [12]).…”

Recent years have brought more attention to new damage detection approaches based on nonlinear phenomena associated with Shear Horizontal (SH) waves. Many nonlinear effects–previously observed in ultrasonic wave propagation–have been considered for structural damage detection. The major effort has been put on classical nonlinear effects, such as higher harmonic generation. More recently, nonlinear vibro-acoustic modulation and modulation transfer mechanisms have been also observed in SH wave propagation. However, these phenomena have not been used for structural damage detection. The paper attempts to fulfill this gap. The proposed method involves two excitation waves. The low-frequency pumping wave is used for damage perturbation. In addition, high-frequency SH wave is used as a probing wave. The probing wave is modulated by the pumping wave in the presence of structural damage. The method is used in the paper for fatigue crack detection in metallic structural components. The results demonstrate that the proposed approach has a potential for structural damage detection. Previous research work demonstrates that classical nonlinear effects (e.g., higher harmonic generation) observed in SH waves offer better sensitivity to material microdefects than similar effects observed in longitudinal wave propagation. Therefore, it is anticipated that non-classical nonlinear affects associated with SH wave propagation will show similar potential. However, more research work is needed to confirm this assumption.

“…Besides, it can be described by high-order elastic constants or nonlinear ultrasonic coefficients [24]. The contact nonlinearity of solids mainly comes from the nonlinear stressstrain of cracks, interfaces, and contact surfaces [25,26], which reflects the local defect characteristics of materials. The existence of defects will lead to strong nonlinear distortion when ultrasonic interacts with it.…”

The dewetting damage of solid propellant under loading is a key factor affecting the constitutive properties of solid propellant, and it will weaken structural integrity of solid rocket motor charge. The quantitative characterization of its evolution process has always been a very active research field. In this study, a nonlinear ultrasonic (NLU) method is proposed to investigate and monitor in real‐time the nonlinear dynamic response of solid propellant. The NLU parameter, which can evolve dewetting damage, is expressed by some physical quantities such as the frequency peak, the propagation distance and so on, and is recorded at different strain in the tensile tests of the round rod solid propellant specimens. Then, the initial dewetting point, characteristic dewetting point and characteristic dewetting rate are defined to characterize the dewetting performance. The results show that NLU parameter changes continuously with the evolution of tensile process and increases sharply at the initial dewetting damage point. By analyzing the data, an empirical formula characterizing the variation law of NLU parameter with strain is proposed, which is well fitted to the experimental data under different strain rates. In addition, relevant numerical simulation is carried out, and the simulation results verify the feasibility of the NLU method.

“…Thus, the authors focused on the symmetric hysteretic model presented by Solodov et al [26], which after the experimental analysis was modified to an asymmetric hysteretic model. The choice was based on the findings presented by Klepka et al [10], where the hysteretic motion between two surfaces was shown via experimental investigation. Furthermore, the time periods of the stick and slip motions were pointed out in the displacement and velocity responses of the analyzed system.…”

Prediction of higher-order harmonics generation due to contact stiffness hysteresis using Harmonic Balance: theory and experimental validation

et al. 2021

In the presented paper, an analytical approach based on the Harmonic Balance method is used to evaluate amplitudes of higher-order harmonics generated due to the interaction of a propagating shear wave with surfaces in frictional contact. The motion between surfaces is initially assumed to be of symmetric hysteretic stick-and-slip type. Experimental investigation is performed on steel samples with prepared contact surfaces, in order to validate the introduced solution approach. It shows that the hysteretic behavior obtained from the experiment exhibits asymmetric characteristic features. Consequently, a new asymmetric description of the hysteretic stress-strain relation is developed and used to confirm these findings. As a result, both qualitative and quantitative agreement between considered investigation methods are achieved. Finally, the identification study shows the impact of higher-order harmonics on particular features of the stiffness hysteresis.
