Abstract

The paper presents a method for assessing the probability of fracture of structural components of technical systems subjected to monotonic and cyclic loading, which permits taking into account the scatter of mechanical properties of materials and the size of macrodefects passed into operation by means of nondestructive testing. The presented method can be used in the implementation of probabilistic and risk-based approaches to ensuring strength, service life and safety of technical systems in real operating conditions and in adjusting standard operating programs in terms of selecting the frequency and scope of non-destructive testing.

考虑材料力学性能和残余缺陷的统计散点，评估结构部件疲劳断裂的概率

摘要

本文提出了一种评估技术系统结构部件在单调和循环载荷下的断裂概率的方法，该方法允许通过无损检测的方式考虑材料力学性能的分散性和通过运行的宏观缺陷的大小。所提出的方法可用于实施基于概率和风险的方法，以确保实际操作条件下技术系统的强度、使用寿命和安全性，并在选择无损检测频率和范围方面调整标准操作程序.
