Effect of Rigidity and Inhomogenity on the Propagation of Love Waves in an Irregular Fluid Saturated Porous Isotropic Layer

Ravinder Kumar, Dinesh Kumar Madan, Jitander Singh Sikka


In the present paper, we study effect of inhomogenity and rigid boundary on propagation of Love waves in a fluid- saturated porous isotropic layer over a semi-infinite non-homogeneous elastic medium with an irregularity. The rectangular irregularity has been taken in the half-space. The dispersion equation for Love waves is derived by perturbation technique followed by Fourier transformation. It can be seen that the phase velocity is strongly influenced by the wave number, the depth of the irregularity, inhomogenity parameter and the rigid boundary. The variations of dimensionless phase velocity against dimensionless wave number are shown graphically for different size of rectangular irregularities and inhomogenity parameter with the help of MATLAB.
