Micromechanical inspection of incremental behaviour of crushable soils [PDF]

, 2019
In granular soils grain crushing reduces dilatancy and stress obliquity enhances crushability. These are well-supported specimen-scale experimental observations.

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Extended Kelvin–Voigt Model for Simulating Thermally Accelerated Creep in Fine‐Grained Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1843-1854, March 2026.
ABSTRACT The subsurface undergoes temperature variations in many situations due to anthropogenic and natural causes, which strongly influence the long‐term behavior of soils. These phenomena can involve temperature anomalies in the ground across distances of a few meters, as in the case of nuclear waste repositories, to distances encompassing entire ...

State-dependent fractional plasticity model for the true triaxial behaviour of granular soil

Archives of Mechanics, 2019
The fractional plasticity was proposed to model the stress-strain behaviour of granular soils, but only within the scope of classical triaxial loading condition.

Determination of stress state in deep subsea formation by combination of hydraulic fracturing in situ test and core analysis: A case study in the IODP Expedition 319

, 2013
[1] In situ test of hydraulic fracturing (HF) provides the only way to observe in situ stress magnitudes directly. The maximum and minimum horizontal stresses, SHmax and Shmin, are determined from critical borehole pressures, i.e., the reopening pressure

The Effect of Graphene on the Fatigue Response and Failure Mechanism of Composite Materials: A Review

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 933-962, March 2026.
ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that

Electrospun Composite Lavandula Angustifolia Mill. Extract/PVP Nanofibers

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
This study presents novel fast‐dissolving nanofibers electrospun from polyvinylpyrrolidone (PVP) loaded with crude lavender extract. The fibers form an amorphous solid dispersion, disintegrate within 1.5 s, and release 70%–90% of their payload within 5 min, significantly outperforming the pure extract.

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...
