A　higher　order　asymptotic　analysis　with　separable　variable　form　is　presented　in　this　paper　for　crack　tip　mechanics　fields　under　mixed　mode　creep　conditions.　By　defining　a　second　order　mode　mixity　factor,　higher　order　term　solutions　are　investigated　by　solving　the　boundary　value　problem.　The　solution　procedure　is　validated　first　and　then　the　characteristics　of　various　kinds　of　second　order　asymptotic　solutions　for　mixed　I/II　creep　crack　tip　field　are　presented　and　discussed.　The　angular　distribution　functions　of　the　second　order　stress　and　the　stress　exponent　for　various　cases　are　given.　Detailed　relations　between　the　amplitudes　of　the　second　order　term　and　the　first　order　term　are　also　discussed.　The　method　and　solutions　given　in　this　paper　encompass　the　higher　order　term　solutions　of　pure　mode　I,　pure　mode　II　and　mixed　mode　I/II.
