[33][34][35][36][37][38][39][40][41] But the derivation of the forced propagation solution excited by horizontal shear waves is complex and difficult, especially in the multilayer cladding structure, which is an exact solution and does not contain any unsolved constants.…”

The forced propagation solution of interfacial shear stress of multilayer cladding structure excited by Love waves is derived by the integral transformation method, and the shear resonance mechanism of interfacial separation is further revealed. The coupling resonance between the excitation frequency and structure intrinsic property causes the peak of interfacial shear stress amplitude, which results in interfacial shear separation at certain frequency bands. It is found that the coupling resonance frequency of interfacial shear stress is only dependent on the inherent properties of the structure, around which the frequency band of interfacial shear separation is formed. The coupling resonance frequency decreases with the increase of the cladding thickness or shear wave velocity difference between the cladding and substrate. The influence of cladding material parameters on interfacial shear stress is greater than that of matrix material parameters. The experimental results support the theoretical analysis results. The conclusions presented could have potential applications in ultrasonic deicing/defrosting/de-sanding and/or coatings protection.

“…Recently, various researchers have investigated Love waves in many different media, viz., Chatterjee and Chattopadhyay (2018) studied the effect of curved boundaries on the particle displacement due to Rayleigh and Love-type wave propagation in a reinforced composite material, Chattopadhyay et al (2018) studied the effect of different types of heterogeneity on the propagation of Love waves using the Debye Asymptotic Expansion approach, Chattaraj and Samal (2016) studied the propagation of Love waves in an initially stressed anisotropic porous irregular layer, Kielczyn´ski (2018) presented a theoretical model for Love-type wave propagation in lossy waveguides consisting of a viscoelastic layer and Pandit et al (2017) explored the existence and propagation of Voigt-type viscoelastic Love waves in a prestressed functionally graded orthotropic layer over porous substrate. Some other problems within the context of Love wave propagation have been attempted by Kielczyn´ski and Cheeke (1997), Rushchitsky (2013), Shams (2016), Kaptsov and Kuznetsov (2015) and Vaishnav et al (2016). The importance of nonlocality and the naturally occurring layered structure of porous rocks in geophysical settings has triggered us to attempt the considered problem.…”

The propagation of Love-type waves in a nonlocal elastic layer with voids resting over a nonlocal elastic solid half-space with voids has been studied. Dispersion relations are derived using appropriate boundary conditions of the model. It is found that there exist two fronts of Love-type surface waves that may travel with distinct speeds. The appearance of the second front is purely due to the presence of voids in layered media. Both fronts are found to be dispersive in nature and affected by the presence of the nonlocality parameter. The first front is found to be nonattenuating, independent of void parameters and analogous to the Love wave of classical elasticity, while the second front is attenuating and depends on the presence of void parameters. Each of the fronts is found to face a critical frequency above which it ceases to propagate. For a specific model, the variation of the phase speeds of both the fronts with frequency, nonlocality, voids and thickness parameters is shown graphically. Attenuation coefficient versus frequency for the second front has also been depicted separately. Some particular cases are deduced from the present formulation.
