A　multiaxial　cycle　counting　method　was　proposed　by　path-dependent　line　integral　(PDLI).　In　the　proposed　PDLI　multiaxial　cycle　counting　method,　the　length　increment　of　loading　path　is　assigned　a　positive　or　negative　sign　in　the　strain　space,　and　the　interval　from　zero　to　the　maximum　value　of　PDLI　is　defined　as　a　half-cycle.　A　very　concise　recursive　algorithm　is　provided　to　implement　the　proposed　multiaxial　cycle　counting　method.　The　experimental　verification　showed　that　the　proposed　multiaxal　cycle　counting　method　was　used　to　count　multi-axial　cycle,　which　can　obtain　satisfactory　life　prediction　results　under　multiaxial　variable　amplitude　loading.　In　addition,　the　PDLI　multiaxial　cycle　counting　method　can　be　reduced　to　a　uniaxial　rainflow　counting　form.
