Considering the federal government s investment in the expansion of the railway network with the growth acceleration program (PAC2) and with the investment in logistics program (PIL), numerous surveys involving railways have been developed in the country, including in the area of materials, such as the rail ballast, object of study of this project. In parallel, research focused on computational modeling has been developed in order to optimize the evaluation of the behavior of materials. This dissertation aims to develop computational models to evaluate the ability of the discrete element method to reproduce the mechanical behavior of cyclically loaded rail ballast, based on a cyclic triaxial test. The study analyzed the mechanical behavior of two rail ballast granulometric distributions, the first being suggested by Indraratna et al. (2004), regarding changes to improve Australian regulations, while the second, uses the Brazilian legislation. The computational model was developed in WooDEM software (2012). Mechanical analysis of the rail ballast behavior was performed considering the coordinates of the particles in relation to time and depth in order to determine the displacement generated by the cyclic loading.
