Lopsidedness of self-consistent galaxies by the external field effect of clusters

, 2017
Adopting Schwarzschild's orbit-superposition technique, we construct a series of self-consistent galaxy models, embedded in the external field of galaxy clusters in the framework of Milgrom's MOdified Newtonian Dynamics. These models represent relatively

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 ...

Fractal Characteristics and Energy Evolution Analysis of Rocks under True Triaxial Unloading Conditions

Fractal and Fractional
To investigate the mechanical properties and energy evolution laws of rocks under true triaxial unloading conditions, a study was conducted using a true triaxial rock testing system on three different types of rocks: coal, sandy mudstone, and siltstone ...

Ellipsoidal halo finders and implications for models of triaxial halo formation

, 2013
We describe an algorithm for identifying ellipsoidal haloes in numerical simulations, and quantify how the resulting estimates of halo mass and shape differ with respect to spherical halo finders.

The Impact of Soil Anisotropy on Surface Settlements Induced by Tunnelling: A Revealing Parametric Study and Nomogram Development to Improve Modelling Practice

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 1218-1228, 10 February 2026.
ABSTRACT Natural soils often exhibit clearly anisotropic mechanical properties, yet this characteristic is frequently overlooked in numerical models due to the practical challenges of determining anisotropic parameters. As a result, the influence of anisotropy remains difficult to anticipate, and engineers have limited tools to incorporate it into ...

Bayesian Neural Network Prediction and Uncertainty Analysis of Bio‐Cemented Soil Strength

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 3, Page 1349-1366, 25 February 2026.
ABSTRACT Microbially induced carbonate precipitation (MICP) has emerged as a promising ground improvement technique, with MICP‐treated soils exhibiting substantial enhancements in strength. However, experimental results revealed significant variability in strength outcomes of MICP‐treated soils, even under identical treatment conditions and soil ...

Progressive damage and fracture behavior of brittle rock under multi-axial prestress constraint and cyclic impact load coupling

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
To explore the progressive damage and fracture mechanics characteristics of brittle rock materials under combined dynamic-static loading. Taking account of the coupling effect of the constraint states of uniaxial stress (σ 1 ≥ σ 2 = σ 3 = 0), biaxial ...

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Ellipsoidal configurations in the de Sitter spacetime

, 2006
The cosmological constant $\Lambda$ modifies certain properties of large astrophysical rotating configurations with ellipsoidal geometries, provided the objects are not too compact.

The Influence of Elevated Temperature on Time‐Dependent Compaction Creep in Bleursville Sandstone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The inelastic compaction of sandstone in the upper crust typically occurs at depths where temperatures range from approximately 50°C $50{}^{\circ}\mathrm{C}$ to 150°C $150{}^{\circ}\mathrm{C}$. Previous experimental studies have shown that even this modest temperature increase can reduce the yield stress required to initiate inelastic ...
