Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3738-3750, September 2026.
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, Volume 111, Issue 9, Page 3944-3967, 1 September 2026.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Hierarchical Cross-Modal multianchor distillation for rail surface defect detection

For red–green–blue with depth (RGB-D) rail surface defect detection (RSDD), most models focus on improving accuracy, while ignoring computational costs. To address this gap, we introduce a hierarchical cross-modal multi-anchor distillation network (HCMD)

Survey on vision-based railway track defect detection

智能科学与技术学报
The detection of train track defects is of great significance to the safety of rail transportation, but current manual inspection can no longer meet the complex and heavy track inspection requirements.
