The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Experimental Observations in Stress Intensity Factor Determination Considering Plasticity‐Induced Crack Closure

Strain, Volume 61, Issue 5, October 2025.
This paper investigates the influence of plasticity‐induced crack closure on stress intensity factor evaluation using an experimental–numerical approach with digital image correlation (DIC). Fatigue crack growth tests under constant‐ΔK conditions were carried out on aluminium and steel specimens to isolate shielding effects.
