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 ...
