Influence of Porous‐Layer Permeability and Thickness on Stability and Load‐Bearing Capacity of a Porous air Bearing

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The paper deals with the simulation of porous journal bearings by solving the Reynolds and Darcy equations in conjunction with the continuity equation. To find the solution, the solution domain is discretized using the finite volume method.

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5891-5918, November 2026.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

Heat Treatment and Manufacturing Variability in Gearbox NVH: An Evidence‐Aware Critical Review and Validation‐Oriented Modeling Roadmap

Engineering Reports, Volume 8, Issue 10, October 2026.
Heat treatment and manufacturing variability influence gearbox NVH primarily through distortion, surface integrity, and evolving tooth‐flank geometry. This evidence‐aware review links material state and nonuniform wear to contact excitation, transmission error, structural response, and radiated noise within a validation‐oriented multiscale framework ...
