This　paper　presents　a　numerical.　analysis　of　damage　evolution　process　of　composite　laminated　plate　under　a　low-velocity　impact　using　the　finite　element　method　and　the　first-order　shear　deformation　theory.　Various　types　of　damages　including　delamination,　matrix　cracking,　fiber　failure　and　their　influences　on　the　mechanical　behavior　of　the　plate　are　studied.　A　simulation　technique　is　proposed　to　model　the　damage　initiation　and　evolution,　and　a　computer　program　is　developed　and　successfully　used　for　long-fiber　reinforced　carbon/epoxy　composite　laminated　plate　with　arbitrary　stack　sequence　and　fiber　orientation.　Validations　against　experiment　results　show　that　the　proposed　approach　is　capable　of　giving　accurate　prediction　of　impact　damage　behavior.
