The　constant　length　crack　steadily　propagating　in　an　anisotropic　body,　acted　on　at　infinity　by　uniform　biaxial　and　shear　loading,　is　investigated.　The　analytical　solutions　to　the　dynamic　crack　tip　stress　fields　and　displacement　fields　are　derived.　The　obtained　crack　tip　fields　contain　second　order　term,　and　are　unified　and　applicable　to　the　analysis　of　the　crack　tip　fields　of　anisotropic　material,　orthotropic　material　and　isotropic　material　under　dynamic　or　static　load.　Crack　propagation　characteristics　are　represented　by　crack　propagation　velocity　M　and　fiber　direction　alpha.　The　faster　the　crack　velocity　is,　the　greater　the　dynamic　stress　components　and　dynamic　displacement　components　around　crack　tip　is.　Distributions　of　the　stress　fields　and　displacement　fields　vary　with　M　and　alpha　but　the　inclinations　of　stress　and　displacement　distribution　are　almost　the　same.　The　effects　of　biaxial　loading　coefficient　on　crack　tip　fields　are　also　considered.　(C)　2012　Elsevier　Masson　SAS.　All　rights　reserved.
