The role of particle breakage on the shear behaviour of coarse granular materials: A micromechanical investigation

Conference Paper


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.
