<jats:p>This paper investigates the compressive strength of concrete in a 3-dimensional contact problem using the Discrete Element Method (DEM). This method was chosen because it can simulate the development of a single fracture up to massive fragmentation, including cracks pattern and coalition. The experimental test consisted of four cubes with 150x150x150 mm in dimensions, the constant of axial load applied to each specimen of 0.05Po up to 0.70Po. The data analysis has been carried out in Discrete Element and opensource three-dimensional code (YADE). The spherical Particles were used to the material models of concrete cubes. The pulse velocity parameter proposed to determine the behavior of the material during loading. The DEM and pulse velocity results illustrate the conformity of the relationship between stress and strain, deformation characteristics, and compressive strength of concrete.</jats:p>
