To increase the prediction accuracy of small-number sample life data, improved backward
statistical inference approach (ISIA) was formulated using the modified distribution …

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 …

Carbide-free bainite (CFB) steel with metastable austenite and refined microstructures has
been demonstrated to be a promising alternative to conventional pearlitic rail and wheel …

The remaining life assessment of damaged railway axles is an important topic primarily
because of extending the maintenance interval. However, the fatigue resistance of surface …

Deep rolling is a frequently used post-treatment process to increase the service life of
railway axles. Through the process application, the surface roughness is reduced, the …

To evaluate the inspection interval and safety margin of a railway press-fitted axle with
fretting cracks, we conducted a fretting fatigue crack growth simulation and residual life …

Foreign object damage (FOD) introduced in service, indentations, and nicks encountered
during maintenance are typical defects leading to pre-scrap of high-speed railway axles. A …

This work presents the design of a scaled wheel axle fretting fatigue test equipment that
takes into account the complicated load boundary conditions of high-speed train axles …

Impact damage are critical for damage tolerance assessment of high-speed train axles.
Flying ballast impact damage on railway axles produce geometry discontinuities, which …

To predict the fretting fatigue crack growth (FFCG) life of railway axles, a series of interrupted
fatigue experiments were conducted on scaled railway axles. Subsequently, the evolutions …
