Effect of particle shapes on the resilient behaviour of aggregate materials

This paper presents the results of numerical simulations of the resilient modulus test using the discrete element method to assess the effect of particle shapes on the resilient behaviour of aggregate materials. The simulations were performed on two assemblies made of individual circular particles and clusters composed of three circular particles linked together (prescribing one big triangular element), respectively. The assemblies were subjected to a hydrostatic confining pressure and then to repetitive loading.Ce document pr\ue9sente les r\ue9sultats de simulations num\ue9riques de l'essai de module de r\ue9silience au moyen de la m\ue9thode d'\ue9l\ue9ments discrets, dans le but d'\ue9valuer l'incidence de la forme des particules sur le comportement r\ue9silient des mat\ue9riaux du type granulat. Les simulations ont \ue9t\ue9 r\ue9alis\ue9es sur deux (2) ensembles faits respectivement, l'un, de particules circulaires individuelles, et l'autre, d'agglom\ue9rats r\ue9unissant trois (3) particules circulaires (\ue9tablissant un [1] gros \ue9l\ue9ment triangulaire). Les ensembles ont \ue9t\ue9 soumis \ue0 une pression de confinement hydrostatique, puis \ue0 des charges r\ue9p\ue9t\ue9es.Peer reviewed: YesNRC publication: Ye
