Wave propagation and thermal behavior in nonlocal thermoelastic porous media under moving heat sources with three-phase-lag and Green–Naghdi models (opens in new tab)

This study examines thermoelastic wave propagation in a nonlocal porous thermoelastic half-space subjected to a moving heat source using two advanced theoretical models: the three-phase-lag (3PHL) heat conduction model and the Green–Naghdi type III theory. Analytical solutions for the physical field variables are derived via normal mode analysis. The work highlights the role of nonlocal effects in porous media and presents a comparative assessment of the two thermoelastic frameworks. Numerica...
