Study on the Low Cycle Fatigue Damage of Nodular Cast Iron Based on Elastic Modulus
The influence of fatigue ratio on the low cycle fatigue damage of nodular cast iron was investigated by measuring the elastic modulus. The results indicated that the elastic modulus of nodular cast iron is a sensitive parameter to the fatigue damage at low cycle. The fatigue damage variable of nodular cast iron increases with cycle ratio. At the beginning and end period of cycling, the damage of nodular iron increases sharply, and in the range of 0.2- 0.8 cycle ratio, the fatigue damage grows gradually.
