Bright and Dark Solitary Love Waves in a Heterogeneous Semi-Space Coated with a Heterogeneous Elastic Layer

The propagation of nonlinear Love waves in an elastic, vertically heterogeneous crust laid upon semi-space is considered. By employing the multiple scales method, amplitude function represented by a Schrödinger equation which includes material and heterogeneity parameters layered its coefficients. This study numerically investigates influence as well properties media on presence bright dark solitary waves. Moreover, remarkable effects both layer wave evolution solions are graphically shown.
