Numerical Investigation of the Influence of Interparticle Cohesion During the Shear Behavior of Granular Soil

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 9, Page 4020-4035, 25 June 2026.
ABSTRACT Interparticle cohesive forces play a crucial role in governing the shear behavior of many soils; however, quantifying this effect remains challenging due to limited microscopic insights available from laboratory experiments. In this context, the current study aims to investigate the influence of microscale cohesion on the shear response using ...

Evading Strength–Ductility Trade‐Off in Titanium Matrix Composites via High‐Critical Resolved Shear Stress Dislocation Promotion and Grain Subdivision

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The strength and ductility trade‐off in titanium matrix composites (TMCs) is a critical factor limiting their widespread application. In this study, a (TiB + TiC)/Ti–6Al–4V composite with an optimal balance between strength and ductility was engineered via multi‐directional forging.
