This paper deals with the application of meshless generalized finite difference (GFD) method for laser pulsesinduced thermoelastic wave propagation in porous materials. The governing and constitutive equations are derived for a porous rod using Moore-Gibson-Thompson (MGT) theory of coupled thermoelasticity and Love-Bishop elasticity theory for the first time. The porous rod is subjected to laser shock pulses at one of its ends. The dynamic volume fraction balance equation and the effect of porosities are taken into account to derive the MGT-based heat conduction model in porous materials. The GFD is employed to solve the governing equations in Laplace domain and then the obtained fields’ variables are transferred to time domain using Talbot Laplace inversion technique. The transient behaviors of all fields’ variables such as displacement, temperature and voids’ volume fraction are obtained for various values of the time relaxation parameter in the MGT theory. Also, propagations of thermoelastic wave fronts in displacement, temperature and volume fraction are illustrated at various time steps. To verify the proposed solution approach, the derived governing equations and results, a comparison with a good agreement is conducted in the paper.
