Investigation on Fatigue Properties of Corrugated Board Structure

The fatigue properties of corrugated board structure were discussed through vibration fatigue damage tests,fatigue residual strength tests,and multi-level loads fatigue damage tests.Under a certain frequency and different loads case,the fatigue lives of the corrugated board structure were obtained.Finally,the F-N curve and model of fatigue damage were presented.The trend and the range of fatigue residual strength of the corrugated board structure were founded and analyzed after a certain number of fatigue vibrations.The applicability of Miner's ruler on multi-level stress fatigue damage tests of corrugated board structure was discussed,and the effect of loading sequence on the fatigue life was discussed.
