| Popis: | In the present paper, the two different theories (coupled theory and Green–Lindsay theory with two relaxation times) are applied to study the deformation of a generalized piezo-thermoelastic rotating medium under the influence of magnetic field. The normal mode analysis is used to obtain the expressions for the displacement components, the temperature, the stress, the strain components, the electric potential and the electric displacements. Numerical results for the field quantities are given in the physical domain and illustrated graphically. Comparisons are made with the results predicted by coupled and Green–Lindsay theories in the presence and absence of rotation as well as magnetic field. |
