In the present investigation, the constitutive relations and field equations for micropolar generalized thermodiffusive are derived and deduced for the Green and Lindsay (G—L) theory, in which thermodiffusion are governed by four different relaxation times. The general solution to the field equations in micropolar generalized thermodiffusive is investigated by applying the Laplace and Fourier transforms as a result of concentrated normal force, or thermal point source or potential point source. To get the solution in the physical form, a numerical inversion technique has been applied. The components of displacement, stress, temperature distribution, and chemical potential for the G—L theory and coupled thermoelasticity theory on these quantities have been depicted graphically to show the impact of micropolarity and diffusion. Some special cases are also deduced from the present investigation.
