Fatigue Assessment of Welded Joints Subjected to Multiaxial Loading Conditions through the Effective Critical Plane Approach

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Reliable fatigue design of welded components under multiaxial loading demands local criteria able to capture both the stress gradient at the weld notches and the influence of a complex loading condition including non proportionality of the stress‐strain load history. The Effective Critical Plane (ECP) approach, based on a stress averaging over

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Electrostatic Actuation Induces Competing Adhesion and Vibration Regimes at Fingertip Contact

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
Electric fields modulate fingertip–surface contact to create artificial touch sensations. The mechanisms underlying electrostatic friction, however, remain unclear. Direct imaging and friction measurements under oscillating electric fields showed that adhesion dominates at high frequencies, while vibration contributes substantially at the lower ...
