摘要：

On　the　basis　of　the　continuum　fatigue　damage　theory,　a　nonlinear　uniaxial　fatigue　cumulative　damage　model　is　first　proposed.　In　order　to　describe　multiaxial　fatigue　damage　characteristics,　a　nonlinear　multiaxial　fatigue　cumulative　damage　model　is　developed　based　on　the　critical　plane　approach.　The　proposed　model　can　consider　the　multiaxial　fatigue　limit,　mean　hydrostatic　pressure　and　the　unseparated　characteristic　for　the　damage　variables　and　loading　parameters.　The　recurrence　formula　of　fatigue　damage　model　was　derived　under　multilevel　loading,　which　is　used　to　predict　multiaxial　fatigue　life.　The　results　showed　that　the　proposed　nonlinear　multiaxial　fatigue　cumulative　damage　model　is　better　than　Miner＇s　rule.　©　Higher　Education　Press　2006.
