The fatigue crack propagation threshold Δ K th is of paramount importance for any kind of
damage tolerant design, but in contrast to this importance, the determination and application …

The paper gives an overview on safe life and damage tolerance methods applied to railway
axles. It describes failure scenarios due to fatigue crack initiation and propagation. Besides …

The effects of environment (in air and 3.5 wt% NaCl solution) and artificially-induced surface
scratches are investigated on the fatigue properties of railway EA4T (also called 25CrMo4) …

The synergistic combination of mechanical fatigue stresses and environmental agents acting
together can be more detrimental than that of the summation of the contributions of each …

The effects of corrosion pits on the fatigue life of pre-corroded Q235 steel plates were
investigated. 3D profile measurements were conducted to obtain the distribution and …

从铁路车辆的安全运用及服役评估出发, 论述了转向架部件(如构架, 车轴等)
的抗疲劳评估及应用进展, 重点分析了合金钢EA4T 车轴和碳素钢S38C 车轴的设计理念差别 …

Fatigue is a classic and longstanding issue, which challenges railway axles' structural
integrity. In spite of its almost 200 years of research history, it has always been a hot topic …

The fatigue properties and residual stress relaxation behavior of EA4T axle steel treated by
ultrasonic surface rolling process (USRP) are investigated in air and corrosive …

Understanding the corrosion fatigue mechanism of rail materials is of great importance to
guide the assessment of the structural integrity of modern railway components. To this …

In this paper, an improved continuum damage mechanics (CDM) model for predicting the
corrosion-fatigue life of high-strength steel wires is proposed considering the effects of both …
