The present paper is devoted to the determination of displacement, stresses and temperature from three dimensional anisotropic half spaces due to presence of heat source. The normal mode analysis technique has been used to the basic equations of motion and generalized heat conduction equation proposed by Green-Naghdi model-II [1]. The resulting equation are written in the form of a vector –matr...

Extended shallow water wave equations are derived, using the method of asymptotic expansions, from Euler (or wave) equations. These extended models valid one order beyond usual weakly nonlinear, long approximation, incorporating all appropriate dispersive and nonlinear terms. Specifically, first we derive Korteweg–de Vries (KdV) equation, then proceed with Benjamin–Bona–Mahony Camassa–Holm in (...

In this paper, we present a fully discrete second-order finite-difference scheme with fast evaluation of the convolution involved in absorbing boundary conditions to solve one-dimensional linearized Green-Naghdi system. The Padé expansion square-root function complex plane is used implement convolution. By introducing constant damping parameter into governing equations, convergence analysis dev...
