摘要
为将Weibull统计应用于塑性材料的强度分布规律分析,利用贝叶斯统计方法和第四强度理论对Weibull统计理论进行修正,并用Q235钢的屈服强度进行验证。结果发现:所得到的Weibull似然统计可以很好地描述Q235钢的强度分布。
The Weibull statistics modified by Bayesian statistics and 4th strength law was adapted to analyze the strength distribution of plastic materials, and then validated by yield strength of Q235 steel. The Weibull likelihood statistics can describe well the distribution of the strength of Q235.
