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 ...

Integrated routing of heavy electrical and diesel trucks in forest transports

International Transactions in Operational Research, Volume 33, Issue 5, Page 3088-3109, September 2026.
Abstract Fossil‐free forestry transports are important to reach climate goals. In Sweden, road transports account for around 50% of the industry's CO2 emissions and almost 20% of the road freight volumes. Previous studies have shown that electrification is a cost‐effective way for carbon abatement, while at the same time the requirements for ...

‘Turnaround’ of Indian Railways: Increasing the Axle Loading [PDF]

Axle loading had contributed significantly to the ‘turnaround’ of the Indian Railways (IR) in the two years 2004-06. As the Minister of Railways (MR) stated, “A one ton extra loading per wagon implied additional revenue of Rs 500 crore per annum for IR.”

Safe speed determination for emergency steering of heavy trucks on wet curved roadways

Advances in Mechanical Engineering
Current highway design standards employ point-mass models that neglect complex lateral load transfers during collision avoidance. To address this, an integrated analytical framework was developed to determine maximum safe operating speeds for heavy ...

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Evolution and Influence Analysis of Skid Resistance Performance in Steel Slag Ultra‐Thin Wearing Course Based on XGBoost‐SHAP Framework

Applied Research, Volume 5, Issue 4, August 2026.
An XGBoost‐SHAP framework accurately predicted skid resistance evolution in steel slag ultra‐thin wearing courses under accelerated loading. Surface texture amplitude (Rz, Rq) and loading cycles dominated BPN variation, while 50% steel slag replacement provided a cost‐effective balance between anti‐skid durability and material use.

Economic Effects of Lifting the Spring Load Restriction Policy in Minnesota [PDF]

Spring load restrictions (SLR) regulate the weight per axle carried by heavy trucks during the spring thaw period. This policy aims to reduce pavement damage caused by heavy vehicles and extend the useful life of roads, but it also imposes costs on the ...
