paris formula meaning in English
帕里斯公式
帕瑞斯公式
Examples
- The crack - growth increment of crack - line is computed by paris formula followed by fitting using three - time b - spline function
根据以上思想方法，编写了具有较高的计算效率和精度的数值模拟程序。 - Secondly , the influences of the random parameters on fatigue propagation are discussed in the fatigue propagation paris formula
其次，论述了疲劳裂纹扩展公式中各随机参数对疲劳扩展速率的影响。 - By an example , each parameters are randomized in the paris formula , and the propagation life of fatigue of the structure is prognosticated on the presented reliability
通过算例，将疲劳裂纹扩展速率公式中的各个参量全部随机化，并预测构件在给定可靠度下的疲劳裂纹扩展寿命。 - In spite of that , the cracks propagate stably in specimens for all types of tests . thus the paris formula can be used to describe the fatigue crack propagation , and the values of fatigue fracture parameters in the paris formula are regressed by using the results of fatigue damage and stress intensity factors computation
尽管如此，不论对哪种疲劳试验，其试件疲劳裂缝扩展主要表现为稳定扩展，可以运用paris公式描述疲劳裂纹扩展阶段，并利用疲劳损伤数值模拟计算结果和裂缝扩展过程中的应力强度因子回归了疲劳裂缝扩展速率公式中的疲劳断裂参数。 - In the existing literature , the material coefficients are simply considered as constants . yet the material coefficients c and n in paris formula are randomized in this study . using the least square method , the statistical correlation between c and n is obtained through the numerical value collocation
将以往文献中通常看作是确定性的材料系数随机化，通过对大量数据进行数理统计的分析，将疲劳裂纹扩展速率paris公式中材料系数c和n视为随机变量，采用最小二乘法对c和n进行数值拟合，从而得到二者的统计相关性表达式。
