Fatigue fractures were observed at the web-to-head and web-to-foot interface regions of rail steel thermite weld joint on curve tracks in a mass rapid transit tunnel. To investigate these failures, onsite wireless strain measurement was conducted to

Stress concentration induced by geometry irregularity was found near the weld toe of rail welded joints, leading to high risk of fatigue crack initiation. In this research, an integrated fatigue assessment method of rail welds based on the 3D dynamic

This study investigates the structural fatigue crack growth behavior of observed transverse surface cracks in rail steel and thermite weld subjected to in-plane and out-of-plane loading. Stress Intensity Factor (SIFs) solutions were derived from fini

Multiple fatigue cracks are prevalent in welded structures. Current fatigue assessment code procedures employ various simplifications in the treatment of multiple cracks that result in over-conservative life predictions. In this work, crack coalescen

Stress intensity factor and weld toe magnification factor solutions have been developed for T-butt joint geometries using the three-dimensional extended finite element method to model a semi-elliptical weld toe crack in a fillet-welded T-butt joint p

Thermite welding is commonly applied to join running rails together and any failures related to it will result in delay or even catastrophe. In this paper, mechanical properties and microstructures of specimens extracted from plain rail and welding a

In many metro systems worldwide, faulty train doors are among the main causes of train faults. Train doors not closing properly, or not opening, while causing delays and customer dissatisfaction, could also lead to passengers being offloaded for the

Offshore pipelines transfer oil and gas from seabed to production facility on the surface. The long pipelines are formed by welding of pipe segments, where these welded joints are a source of stress concentration and defects from which fatigue cracks

Defects in real mechanical, industrial and aerospace structures frequently have complex shapes. Most real structures are typically prone to multiple fatigue cracks and their propagation can be monitored by observing changes in the structural stiffnes
