Abstract

This study undertakes an investigation into the fatigue life of carbon steel specimens with opposite semicircular edge notches using a combined approach based on experimental and numerical analysis. The study emphasises the determination of stress concentration factors (SCFs) for these notches based on S-N curves of carbon steel, employing a comprehensive method to evaluate their impacts on fatigue performance. Both experimental and numerical methods are applied to understand the influence of notches on fatigue characteristics, yielding insights into potential failure modes and opportunities for design enhancement. The research deepens our comprehension of fatigue mechanics in carbon steel structures, offering valuable perspectives regarding structural engineering and design refinement. The outcomes highlight the significance of integrating experimental testing and numerical simulations to carry out an exhaustive investigation of fatigue behaviour in notched specimens.
具有相对半圆边单缺口矩形板疲劳寿命的分析与数值研究
采用实验与数值分析相结合的方法,研究了带对半圆边缘缺口的碳钢试样的疲劳寿命。研究重点是基于碳钢S-N曲线确定这些缺口的应力集中系数(SCFs),并采用综合方法评估其对疲劳性能的影响。实验和数值方法均用于了解缺口对疲劳特性的影响,从而深入了解潜在的失效模式,并为设计改进提供机会。该研究加深了我们对碳钢结构疲劳力学的理解,为结构工程和设计改进提供了有价值的观点。结果强调了将实验测试和数值模拟结合起来对缺口试件的疲劳行为进行详尽研究的重要性。
