“…Son and Kang (2012) elucidated the propagation of shear wave in a poroelastic layer constrained between two elastic layers. Chattaraj et al (2013) investigated the propagation of Love wave in an initially stressed fluid-saturated anisotropic porous layer with an irregular boundary sandwiched between two isotropic half-spaces. Samal and Chattaraj (2011) obtained the dispersion relation in the form of a ninth order determinant for the propagation of surface wave in fibre-reinforced anisotropic elastic layer between a liquidsaturated porous half-space and uniform liquid layer.…”

The presence of porosity and reinforcement in a medium is an important factor affecting seismic wave propagation and plays vital role in many geophysical prospects. Also, the presence of salt and ore deposits, mountains, basins, mountain roots, etc. is responsible for the existence of corrugated boundary surfaces of constituent layers. Such facts brought motivation for the present paper which deals with the propagation of SHwave in a heterogeneous fluid-saturated poroelastic layer with corrugated boundaries lying over an initially stressed fibre-reinforced elastic halfspace. Closed form of dispersion relation has been obtained and is found in well agreement to classical Love wave equation for isotropic case. The effect of corrugation, wave number, undulation, position parameter, horizontal compressive/tensile initial stress and heterogeneity on phase velocity has been analysed through numerical computation and graphical illustration. Moreover, comparative study exploring the effect of presence and absence of reinforcement in half-space on dispersion curve is the major highlight of the current study.

“…Ben-Hador and Buchen (1999) have established the dispersion of Love and Rayleigh waves in multi-layered models with smooth and weakly nonparallel boundaries using the first-order perturbation theory of Whitham's equation. Propagation of a Love wave in an initially stressed fluid-saturated anisotropic porous layer with an irregular boundary sandwiched between two isotropic half-spaces was studied by Chattaraj et al (2012). Chattopadhyay et al (2011a, b) studied the propagation of horizontally polarized shear waves in an internal magnetoelastic monoclinic stratum with irregularity in lower interface.…”

The present paper deals with the propagation of Love-type wave in an initially stressed irregular vertically heterogeneous layer lying over an initially stressed isotropic layer and an initially stressed isotropic halfspace. Two different types of irregularities, viz., rectangular and parabolic, are considered at the interface of uppermost initially stressed heterogeneous layer and intermediate initially stressed isotropic layer. Dispersion equations are obtained in closed form for both cases of irregularities, distinctly. The effect of size and shape of irregularity, horizontal compressive initial stress, horizontal tensile initial stress, heterogeneity of the uppermost layer and width ratio of the layers on phase velocity of Love-type wave are the major highlights of the study. Comparative study has been made to identify the effects of different shapes of irregularity, presence of heterogeneity and initial stresses. Numerical computations have been carried out and depicted by means of graphs for the present study.

“…Erbas¸et al (2014) established a specialized hyperbolic-elliptic formulation for the wave field and dealt with three-dimensional (3D) analysis of near-resonant regimes of a point load, moving steadily along the surface of a coated elastic half-space. Other than these, many other authors had also elucidated the problem of a moving load including Olsson (1991), Lee and Ng (1994), Selim (2007), Mittal and Jiwari (2009), Chattaraj et al (2012), Kaur et al (2014), Alekseyeva (2007), Andersen et al (2007), Celebi and Schmid (2005), Adam et al (2000) and Chattopadhyay et al (2011).…”

The present paper investigates the effect of initial stress, irregularity depth, irregularity factor and magneto-elastic coupling parameter on the dynamic response due to a normal moving load with constant velocity on the free surface of an irregular magneto-elastic transversely isotropic half-space under the state of hydrostatic initial stress. The expressions for normal stress and shear stress are obtained in closed form analytically. The considerable effect of initial stress, irregularity depth, irregularity factor and magneto-elastic coupling parameter on normal stress and shear stress are computed numerically and depicted by means of graphs. Moreover, comparative study highlighting the effect of various types of irregularity viz. rectangular irregularity, parabolic irregularity and no irregularity on the normal stress and shear stress is a key feature of the study.
