dc.description.abstract | This paper presents Discrete Element Model simulations of packing of rigid sphero-cylinders. The method has been used before but this study considers higher aspect ratios, up to 30. This posed some modelling challenges in terms of stability which were overcome by imposing limits on the particle motion. The results show very good agreement with experimental data in the literature and more detailed in-house experiments for packing volume fraction. Model results on particle orientation are also shown. The model has the potential for predicting packing of fibrous particles and fibre bundles relevant to the preparation of preforms for the production of polymer and metallic matrix composites. Future model developments will include adding flexibility by connecting sphero-cylinders as subelements to describe a particle. |
