  • Discrete element modeling of the single-particle crushing

    01/08/2017· This was caused by the occurrence of tilting of the ballast stone during the compression (caused by crushing of the surface and rebuilding of vertically asymmetrical contacts, even though the initial asymmetrical contacts were already avoided) or infirm contact originating from the roughness of the surface of the ballast stone. Both of these reasons relate to the shape of the ballast stone. Because the exact tilting behavior of a ballast

  • Frontiers Discrete Element Modeling of Permanent

    14/01/2020· Several different factors such as angularity, uniformity of gradation, lower particle strength, coarseness, stress level, and anisotropy govern the crushing of railroad ballast particles (Bohac et al., 2001). The most important of all these factors is the crushing strength of ballast. Appropriate particle crushing strength values can be established by performing the Single Particle Crushing Test (SPCT)
