In　the　Part　II　of　this　paper,　two　typical　specimens,　i.e.　compact　tension　shear　(CTS)　specimen　and　single　edge　notched　(SEN)　specimen,　are　selected　as　the　numerical　cases　to　analyse　the　dominance　of　C*-integral　for　mixed　I/II　creep　crack　under　extensive　creep.　C*-integrals　under　different　loading　angles　are　presented　with　the　same　loading　level　for　CTS　specimens　and　SEN　specimens.　The　equivalent　creep　zone　enlarges　with　the　decrease　of　the　loading　angle,　which　implies　that　the　lower　creep　mixity　occupies　the　larger　equivalent　creep　zone　under　the　same　loading　level.　A　normalized　stress　function　method　based　on　the　FE　calculation　is　given　to　obtain　the　distribution　functions　of　mixed　I/II　creep　crack　tip　fields.　The　comparisons　of　the　FE　solutions　and　HRR　field　are　made　for　CTS　and　SEN　specimens　with　various　crack　depths,　and　it　can　be　found　that　the　loss　dominance　of　C(t)　becomes　remarkable　under　those　cases　close　to　mode　I　loading.　The　Q-parameter　computed　with　the　tangential　stress　is　found　to　be　invalid　to　be　used　as　the　constraint　parameter　for　mixed　mode　creep　crack　under　the　extensive　creep　regime　because　of　the　influence　of　blunting　effect.　The　stress　triaxiality　along　maximum　tangential　stress　(MTS)　direction　is　suitable　to　be　selected　as　the　constraint　parameter　for　the　mixed　I/II　creep　crack　tip　field.　The　stress　triaxiality　is　independent　on　the　radial　distance　even　in　a　wide　range　away　from　creep　crack　tip　along　the　MTS　direction.
