Based　on　the　critical　plane　method,　a　high-cycle　fatigue　criterion　considering　the　effects　of　the　phase　shift　and　mean　stress　on　multiaxial　fatigue　strength　is　proposed　for　hard　metals.　When　the　materials　obey　the　von　Mises　criterion　and　are　subjected　to　proportional　loading　without　the　mean　stress,　the　proposed　criterion　can　be　reduced　to　the　von　Mises　criterion.　The　experimental　data　conducted　under　combined　bending　and　torsion　loading　from　some　studies　were　employed　to　validate　the　applicability　of　the　proposed　criterion.　The　results　demonstrate　that　the　proposed　criterion　has　good　agreement　with　the　experimental　data　under　loading　conditions　with　both　the　mean　stress　and　phase　shift　effects.
