Transient magneto-thermo-elasto-diffusive responses of rotating porous media without energy dissipation under thermal shock

摘要

In this work, transient magneto-thermoelastic responses of a rotating half-space with diffusion and voids whose surface is subjected to a zonal time-dependent thermal shock is investigated in the context of the second type Green-Naghdi thermoelastic theory (without energy dissipation). The solution is obtained by solving the corresponding finite element governing equations of the problem. The transient responses, i.e. temperature, stresses, displacements, mass concentration and chemical potential, the change in volume fraction field, induced magnetic field as well as induced electric field are graphically presented. Comparisons are made between the results obtained in the case of absence and presence of diffusion (rotation) to show the influences of diffusion (rotation) on the magneto-thermoelastic responses.
