Abstract
The three-phase-lag model and Green–Naghdi theory without energy dissipation are applied to study the effect of the gravity field and a magnetic field on a wave propagation in a generalized thermoelastic problem for a medium with an internal heat source that is moving with a constant speed. The medium is a homogeneous isotropic thermoelastic in the half-space. The exact expressions of the displacement components, temperature, and stress components are obtained by using normal mode analysis. Numerical results for the field quantities are given in the physical domain and illustrated graphically in the absence and presence of a magnetic field as well as the gravity field.
