In this paper, the discrete element method (DEM) is coupled with the Lattice Boltzmann method (LBM) to model the cone penetration test (CPT) of a saturated granular media. The coupled numerical model was calibrated using one-dimensional (1D) consolidation theory. The results obtained from the 1D consolidation test simulation showed good agreement with the analytical equation that was proposed by Terzaghi. A series of LBM-DEM simulations were carried out to understand the effect of the penetration rate on the behavior of saturated granular materials during the CPT. The model has predicted a significant influence on the excess pore fluid pressure (Δu) and an insignificant influence on the cone resistance responses (qt) and has qualitatively captured the effect of penetration rate, which was consistent with the experimental data. The simulation results showed that Δu increased with an increase in the penetration rate. The particle displacement and fluid velocity (U) contours have provid
