AbstractThis paper presents the results of numerical simulations of a cyclic loading test. Discrete element modelling (DEM) was used. It permits the consideration of the discontinuous and heterogeneous nature of aggregate materials. The simulations were based on assemblies of circular particles confined between top and bottom rigid boundaries and laterally confined with constant stresses. Contact forces and displacements obey a linear relationship. Furthermore, shear forces were restricted to a maximum value (Coulomb's friction law). Compacted samples were subjected to deviatoric repeated loads. The investigation confirmed the linear relation between normal and shear stiffnesses of particles and the resilient modulus.
