Metal Fatigue Fracture After Revision Total Knee Arthroplasty: A Retrieval Analysis

Journal of Orthopaedic Research, Volume 44, Issue 4, April 2026.
(A) Revision total knee arthroplasty components fracture, promoted by a lack of metaphyseal fixation. (B) Scanning electron microscopy identifies transgranular fatigue crack propagation. (C) Modular junction analysis documents chemical and mechanical conditions associated with a decrease in fatigue strength.

Study on high-low cycle fretting fatigue life of Inconel718 tenon structure

Hangkong gongcheng jinzhan
The turbine blades of aero-engines are subjected to cyclic high-low cycle loads in actual service environments，which is a typical high-low cycle micro motion fatigue condition. The frequent occurrence of fatigue fracture in turbine blades due to fretting

Rock Face Temperature Variability From Long‐Term High‐Frequency Infrared Thermography

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Changes in rock‐surface temperature generate thermal stresses and freeze–thaw conditions that can generate rockfalls. Capturing the full range of temperature variation, from seasonal variability to hourly extremes, is important, but data sets recording such characteristics with sufficient temporal and spatial resolution remain scarce, limiting

Fatigue Crack Nucleation and Growth in Recrystallized Annealed Ti‐6Al‐4V Combat Aircraft Structures

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 4, Page 1460-1471, April 2026.
ABSTRACT In the Swiss Air Force (SAF) F/A‐18C/D Hornet fleet, recrystallized annealed Ti‐6Al‐4V was selected for the wing carry through bulkheads to meet their demanding operational usage profile requirements that included increased airframe strength and toughness.

Crack failure behaviors of Ti–6Al–4V dovetail joints subjected to fretting fatigue and effect of laser shock dimple-textured surface coated with diamond-like carbon film

Journal of Materials Research and Technology
Fretting damage can lead to a reduction in fatigue strength by more than half, due to the increased stress on the fretting surface, which accelerates crack initiation and propagation.

Between IT Engineer and Food Courier: How Remittances Shape the Economic Integration of South Asian Students in Finland

Global Networks, Volume 26, Issue 2, April 2026.
ABSTRACT This study examines the economic integration processes of student migrants from Pakistan and India in Finland—both students on scholarships and those who are self‐funded—drawing on ethnographic fieldwork and life story interviews. Transnational family ties and remittance dynamics are shown to shape varied career pathways, from low‐skilled ...

Simulation of Fretting Fatigue in Conformal and Concentrated Contacts

Tribology Online, 2011
Fretting fatigue is a possible failure mode of rolling bearings, as well as for other machine elements with contacts. For a rotating bearing it normally can occur in the interfaces between outer ring/housing, and inner ring/shaft.

Contact mechanics in fretting fatigue [PDF]

, 2012
This paper studies the contact mechanics in a line contact during fretting fatigue conditions. In literature one can find numerical and analytical solutions of normal and tangential stresses for a variety of loading cases.
