Effect of rotation on plane waves of generalized electromagnetothermoelastics with diffusion for a half-space

This article is aimed at studying the effects of rotation on the model of generalized thermoelastic diffusion for a thermally, isotropic and electrically conducting half-space with rotation at the uniform angular velocity. The rotating half-space is initially placed in an external magnetic field with constant intensity and its bounding surface in contact with a permeating substance is taken to be traction free and subjected to a time-dependent thermal load and chemical potential. The system of Maxwell's equations is given and the generalized electromagnetothermoelastic diffusion coupled governing equations are established. The normal mode analysis is adopted to solve the problems and the exact expressions for the non-dimensional temperature, displacement, stress, induced magnetic field, induced electric field, chemical potential and concentration are gained and represented graphically. The effects of rotation are evaluated by comparing the results obtained in the presence and absence of rotation.
