摘要：Based on fracture mechanics and fuzzy theory, a model of fatigue life is developed to predict the fatigue life of structure. The dangerous point and stress amplitude can be gotten by finite element analysis method. According to fracture mechanics theory, considering fuzziness of fatigue life factors, the Paris' formula is combined with fuzzy theory and the model of fatigue life based on fuzzy theory is developed. The fuzziness of fatigue life factors is considered in the model so the results are more close to real situation. The model offers reference for fatigue life analysis.
