Based　on　the　cycle　counting　method　of　Wang　and　Brown　and　on　the　linear　accumulation　damage　rule　of　Miner,　four　multiaxial　fatigue　damage　models　without　any　weight　factors　proposed　by　Pan　et　al.,　Varvani-Farahani,　Shang　and　Wang,　and　Shang　et　al.　are　used　to　compute　fatigue　damage.　The　procedure　is　evaluated　using　the　low　cycle　fatigue　experimental　data　of　7050-T7451　aluminum　alloy　and　En15R　steel　under　tension/torsion　variable　amplitude　loading.　The　results　reveal　that　the　procedure　is　convenient　for　engineering　design　and　application,　and　that　the　four　multiaxial　fatigue　damage　models　provide　good　life　estimates.
