摘要
在分析材料疲劳破坏具有随机性的基础上，建立了材料疲劳破坏的概率预测模型和灰色预测模型，并通过实例验证，两种预测模型都具有较好的精度，具有一定的理论意义和实际应用价值。
Based on the analysis of metal material having the property of stochastic fatigue failure, the probabilistic prediction model and grey prediction model for fatigue failure of metal material are established. Moreover, it has been verified by experiments that these models both have ed precision, a certian theoretical significance and Value of practical applica- tion.
