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 ...

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 ...

Applying Schwarzschild's orbit superposition method to barred or non-barred disc galaxies
We present an implementation of the Schwarzschild orbit superposition method which can be used for constructing self-consistent equilibrium models of barred or non-barred disc galaxies, or of elliptical galaxies with figure rotation.

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.

The Evolution of Cuspy Triaxial Galaxies Harboring Central Black Holes
We use numerical simulations to study the evolution of triaxial elliptical galaxies with central black holes. In contrast to earlier numerical studies which used galaxy models with central density ``cores,'' our galaxies have steep central cusps, like ...

Micromechanical study of granular assemblies by true triaxial test simulations [PDF]
Geomaterials, such as soils and rocks, are discontinuous and multiphase in nature since they are a mix of particulate elements and different constituents. The discrete nature of geomaterials yields a complex media to deal with regarding predictive capabilities that can only be achieved through expensive computational simulations.

A finite-strain hyperviscoplastic model and undrained triaxial tests of peat
This paper presents a finite-strain hyperviscoplastic constitutive model within a thermodynamically consistent framework for peat which was categorised as a material with both rate-dependent and thermodynamic equilibrium hysteresis based on the data ...
