摘要：

Dispersion　curves　provide　the　fundamental　information　to　describe　the　propagation　of　elastic　waves　through　a　structure.　The　directional　semi-analytical　method　combined　analytical　approach　with　numerical　method　is　very　efficient　in　solving　complex　problems.　In　this　paper,　dispersion　relations　for　three-dimensional　waveguides　with　rectangular　cross-section　are　proposed　by　using　directional　semi-analytical　method.　Results　show　that　a　rectangular　unit　can　be　used　to　compute　the　dispersion　curves　for　rectangular-rod.　Geometric　and　physical　parameters　can　affect　the　dispersion　curves,　and　the　influence　on　different　modes　is　different.　Finally,　the　proposed　method　is　proven　by　the　experiment.　©　2015,　Beijing　University　of　Technology.　All　right　reserved.
