Abstract

In this investigation, aDEM based computer program Particle Flow Code in Two Dimension (PFC2P) has been used to study the cyclic behavior of ballast particles. Angular ballast particles were modeled as clusters of bonded circular particles and degradation of the bonds within a cluster was considered to represent particle breakage. The results of DEM simulations captured the ball(lst behaviour under cyclic loading in accordance with the experimental observations. Furthermore, a relationship has been proposed between, micromechanical parameter, particle displacement vectors and number of bond breakage.
