Abstract

SH wave propagation considering a model comprised of a dry sandy layer, an orthotropic elastic layer and a prestressed dry sandy half-space has been investigated in present problem with dislocation- like imperfectness considered at medium I and medium II’s interface. Expressions for displacement components for layers and half-space are obtained by using variable separation method. Appropriate boundary conditions are used to derive dispersion equation and is used for graphical analysis. Numerical computations are used to depict the several characteristics’ influence on SH wave propagation, such as sandiness, imperfection and pre-stress. Obtained results regarding propagation pattern of SH-waves for the considered geometry due to various parameters serves as the utmost features of this study, having possible applications in material sciences, soil dynamics and geophysics.
