摘要：

High-cycle　fatigue　life　prediction　methods　based　on　different　critical　planes,　including　the　maximum　shear　stress　(MSS)　plane,　the　weighted　average　shear　stress　plane　and　the　Maximum　Variance　shear　stress　plane,　are　compared　by　two　multiaxial　cycle　counting　methods,　i.e.　the　main　and　auxiliary　channels　(MAC)　counting　and　the　relative　equivalent　stress　counting.　A　modified　damage　model　is　used　to　calculate　the　multiaxial　fatigue　damage.　Compared　with　the　experimental　lives　for　7075-T651　aluminium　alloy,　the　predicted　results　show　that　the　MSS　method　together　with　MAC　counting　is　suitable　for　the　multiaxial　fatigue　life　prediction.
