【Abstract】 The applicability of Palmgren-Miner linear accumulation damage criterion used in the calculation of fatigue life of offshore engineering was studied and analyzed. The shortage of using this criterion in the calculating of fatigue life under variable loading was pointed out. The scope of application of Palmgren-Miner criterion was discussed and proposed.更多还原
