On the Mutual Relation Between Contact Ratio and Crack Propagation in the Tooth Root of Spur Gears

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3896-3908, September 2026.
ABSTRACT This work investigates the mutual relationship between contact ratio and tooth root crack propagation in spur gears, with particular focus on the influence of meshing stiffness and load sharing on the tooth root lifetime. An experimental case study originally reported by Rettig, in which SN curves of gears with similar geometry but different ...

Hydrogen‐Enhanced Grain Boundary Conductivity Explains High‐Conductivity Anomalies in Trans‐Lithospheric Shear Zones

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Magnetotelluric (MT) surveys reveal high electrical conductivity anomalies along major trans‐lithospheric shear zones. Given that trans‐lithospheric shear zones are proposed conduits for deep‐Earth volatiles, we employ molecular dynamics simulations to quantify H+ diffusivity and electrical conductivity at olivine grain boundaries.

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Pain Sensitivity Profiles Are Associated With Muscle Biomechanics and Clinical Pain in Persons With Symptomatic Knee Osteoarthritis

ACR Open Rheumatology, Volume 8, Issue 8, August 2026.
Objective There is growing evidence that knee osteoarthritis (OA), a significant source of chronic pain, is only partly explained by joint pathophysiology, varies significantly between individuals and may be partly driven by changes in periarticular tissues.
