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 ...

PERMEABILITY ANISOTROPY OF SHIRAHAMA SANDSTONE UNDER TRUE TRIAXIAL STRESSES
Anisotropic stresses may induce anisotropic permeability of rocks. The present study aims at establishing the relation between permeability tensor and principal stresses for Shirahama sandstone within the pre-yield range. The effects of three principal stresses on the permeability are experimentally investigated using a Mogi-type true triaxial ...

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

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

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

Microlayer Model: A Nonlinear Finite Strain Viscoelastoplastic Formulation for Asphalt
ABSTRACT The microlayer framework is an innovative and powerful approach for the numerical simulation of heterogeneous materials, such as aggregate‐matrix composites across multiple scales. In this study, the microlayer framework is extended for the first time to account for viscoelastic‐elastoplastic material behavior.
