摘要: This paper investigates the propagation of horizontally polarised shear waves due to a point source in magnetoelastic self-reinforced layer lying over heterogeneous half-space. The heterogeneity is caused by consideration quadratic variation rigidity. methodology employed combines an efficient derivation for Green’s functions based on algebraic transformations with perturbation approach. Dispersion equation has been obtained closed form. dispersion curves are compared different values coupling parameters and inhomogeneity parameters. Also, comparative study being made through graphs find effect reinforcement reinforced-free case phase velocity. It observed that assertion classical Love-type wave absence reinforcement, magnetic field heterogeneity. Moreover, some important peculiarities have graphs.
