FIGURE 8 Comparison of the predictive capability of five models for the remaining life of welded joints
Results ofnodular cast iron GS61
Reference28 gives the fatigue loading test data of nodular cast iron GS61. When the loading stress is 352, 320, and 303Mpa, the fatigue life is 112866, 322580, and 588235 cycles, respectively.
Table 3 gives the experimental remaining life fraction and the predicted life fraction of Miner’s rule, the K-R model, Zhu’s model, Li’s model, and the new model.
