RVE　combined　with　finite　element　analysis　(FEA)　is　a　very　popular　method　to　predict　the　mechanical　property　of　the　composite　reinforced　by　short　fibers.　In　the　conventional　method,　generally　the　＇tie＇　approach　is　used.　By　this　method,　the　FE　model　with　high　fiber　aspect　ratio　can　not　be　achieved　and　the　non-convergence　of　the　numerical　calculation　may　appear　because　of　the　complex　mesh.　The　embedded　element　techinique　is　considered　to　be　a　replaceable　method.　Using　this　method,　the　mechanical　behavior　of　composite　with　high　fiber　aspect　ratio　would　be　simulated.　Therefore,　in　this　study,　the　3D　solid　element　was　employed　for　the　FE　model　with　multi　cylinder　particles.　The　comparisions　of　the　Mise　stress　and　the　displacement　between　the　embedded　and　conventional　method　indicate　that　compared　with　the　stress　transfer,　the　simulated　result　of　composite　stiffness　is　more　accurate.　In　addition,　the　effects　of　model　size,　fiber　orientated　angle,　fiber　volume　fraction　and　fiber　aspect　ratio　were　investigated.　The　numerical　results　were　compared　with　the　Mori-Tanaka　model　and　the　good　agreements　verify　the　applicability　of　the　embedded　element　technique　we　studied　in　this　paper.　©　2019　Trans　Tech　Publications,　Switzerland
