| Abstract |
This study develops a micropolar thermoelastic model for porous media with temperature-dependent properties and rotation, solved via normal mode analysis within the framework of the
Refined Lord–Shulman (RLS) hypothesis, which includes one thermal relaxation time. This analytical approach enables detailed investigation of how rotation, porosity, and temperature-dependent
characteristics affect displacement, temperature distribution, microrotation, and stress fields. The
results reveal that including temperature-dependent coefficients significantly alters waves behavior
and stress distributions. The refined Lord–Shulman framework effectively captures finite-speed thermal wave propagation and relaxation phenomena, making the model applicable to advanced problems
in geophysics, biomechanics, and aerospace engineering. |
