Triaxial

An experimentally validated DEM simulation of a monotonic triaxial test on railway ballast including the membrane boundary condition
Discrete element modelling of a monotonic triaxial test is carried out with the aim of studying the stress-strain response of railway ballast in a large-scale tester.
