Study of friction welding [PDF]
, 2007 Friction welding(FW) is a fairly recent technique that utilizes a non-consumable welding tool to generate frictional heat and plastic deformation at the welding location, there by affecting the formation of a joint while the material is in solid state ...

A fast and accurate two-stage strategy to evaluate the effect of the pin tool profile on metal flow, torque and forces in friction stir welding [PDF]
, 2017 Pin geometry is a fundamental consideration in friction stir welding (FSW). It influences the thermal behaviour, material flow and forces during the weld and reflects on the joint quality.

Energetics of the Upper‐Ocean Under Sea Ice: Frictional Dissipation Versus Baroclinic Production
Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.Abstract In polar regions, the presence of sea ice is known to reduce the ocean's eddy kinetic energy (EKE) by enhancing frictional dissipation at the surface. Here, using a coupled ocean—sea ice model, we discuss a mechanism that can instead increase EKE generation under sea ice and, in our simulations, compensates surface dissipation by 69% to 30 ...

Modelling thermomechanical behaviour of Cr-Mo-V steel [PDF]
, 2010 This paper presents a mechanism-based approach for modelling the thermomechanical behaviour of a Cr-Mo-V steel. A set of unified viscoplastic constitutive equations were employed to model dislocation density, recrystallisation and grain size during ...

Droplet, Volume 5, Issue 1, January 2026.Engineered topologies surfaces with special wettability are promising for their ability to precisely customize wetting behaviors and incorporate versatile functionalities, setting them apart from randomly structured surfaces. However, robustness and durability have been hurdles to their broad application.

British Journal of Management, Volume 37, Issue 1, January 2026.Abstract This essay interrogates how extreme events including the COVID‐19 pandemic, climate disasters, and political conflict, amplify structural inequalities in academia. Drawing on critical autoethnographic material from an Early Career Researcher with intersecting marginalisations, we show how crises expose and intensify two mutually reinforcing ...

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.A research gap exists concerning how different chaotic mappings influence the applicability of metaheuristic algorithms, along with inherent limitations of the traditional artificial hummingbird algorithm (AHA). Specifically, blind spots in population coverage and vulnerability to local optima stemming from random initialization.

Numerical simulation and experimental validation of texture in extruded wires of a bcc metal [PDF]
, 2013 We present a comparison between a viscoplastic crystal plasticity finite element simulation of the extrusion process applied to a bcc polycrystal and the experimental evaluation of the preferred orientation (texture) in a tungsten wire by monochromatic ...
