Effect of Magnetic Field on Reflection of Thermo-elastic Waves from the Boundary of a Half-Space Using G–N Model of Type-II for Different Nature of the Boundary Surface

The aim of this paper is to investigate the problem of reflection of plane thermoelastic waves in presence of magnetic field from the boundary of a half-space using Green–Naghdi model of type-II. Analytical solutions for the ratios of the amplitude of the reflected waves to that of incident wave have been obtained in matrix form for stress-free insulated, stress-free isothermal, rigid insulated and rigid isothermal boundaries of the halfspace. Numerical results have been carried out to obtain the values the amplitude ratios only for incident P and SV wave and shown graphically.
