In this study DEM simulations were performed to analyze the liquefaction of granular soils. Three different simulations were carried out: triaxial test (TX), static direct simple shear test (SDSS) and cyclic direct simple shear test (CDSS). The soil selected for the analysis was Monterey #0/30 sand, its calibration was done in the TX by inhibiting particle rotation during the loading phase. After that, the calibrated set of micro-parameters were tested in the SDSS to observe its response in a different test configuration showing good agreement. Subsequently, the material was subjected to strain-controlled cyclic loading simulating the CDSS. In the CDSS, the excess pore pressure was measured following the constant-volume approach in loose, medium and dense samples. Overall, the numerical simulations agreed well with the experimental results.
