Effects of irregularity and anisotropy on the propagation of shear waves

Abstract

The propagation of shear waves differs between geo-media due to layer's structure and irregularity present in different layers. This paper studies the propagation of shear waves in a monoclinic layer with irregularity lying between two isotropic semiinfinite elastic medium. The displacement in the monoclinic layer is obtained by using perturbation technique. Then the dispersion relation is found in the assumed medium and is verified with the standard known results. Finally, effects of wave number and irregularity are studied numerically and the graphs are plotted for all cases. The dispersion curves for different size of irregularity are calculated and compared.
