| Abstract | ||
| In the present study, we discussed the effect of rotation on a nonlocal poro-thermoelastic solid half-space. A two-dimensional problem is applied using the generalization called the three-phase-lag thermoelasticity theory which is according to Choudhuri model (3PHL). The thermoelasiticity of Choudhuri mdel (3PHL) three-phase-lag model is very useful in the problems of nuclear boiling, exothermic catalytic reactions, phonon-electron interactions, and phonon-scattering. The non-dimensional coupled governing equations of motion are solved to get analytical expressions of the displacement components, thermodynamics temperature, the change in volume fraction field, and the stress components with the aid of normal mode analysis. The numerical results are displayed and presented graphically to depict the effect of the rotation and vertical distance on wave propagation in a nonlocal poro-thermoelastic solid half-space. The results show a valuable contribution to the problem of practical design of such structures, to design stiffness, damping, and so on into the right place of the structure by selecting the appropriate material properties. | ||
