Discrete Element Modeling of Permanent Deformation Accumulation in Railroad Ballast Considering Particle Breakage
Particle shape and mineralogy have been found to greatly affect railroad ballast response under train loading. In this research effort, the effect of particle breakage on ballast permanent deformation behavior was studied using the Discrete Element Method (DEM). Real ballast particle shapes were dig...
