The effect of diffusion on micropolar thermoelastic medium under 3PHL model

This article aims to study how a thermoelastic medium having a bipolar nature is impacted by diffusion. It employs an analytical method called normal mode analysis to derive the formula for required physical quantities. The paper utilizes Green‐Naghdi theory (G‐N III) along with the three‐phase‐lag (3PHL) model to solve the existing problem. The comparisons are established graphically for different values of the phase‐lag times, the presence and absence of diffusion, and the time parameter with respect to Green‐Naghdi theory and the 3PHL model.
