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

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
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 ...

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

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
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 ...

Low‐Velocity Impact Response of Nacre‐Inspired E‐Glass/Epoxy Composites With Varying Platelet Sizes

Polymer Composites, EarlyView.
Impact response of nacre‐inspired E‐glass/epoxy composites with different platelet sizes. ABSTRACT This study explores the low‐velocity impact behavior of nacre‐inspired biomimetic platelet composites (NIBPC), using low‐cost E‐glass fiber in chopped strand mat (CSM) form as reinforcement and epoxy resin as the matrix.

Determination of stiffness and strength parameters for the hardening soil model based on the simplicial homology global optimization and triaxial compressive test

Scientific Reports
Constitute model calibration and their parameter determination are essential to scientifically and accurately characterize soil mechanical behavior. However, this is a challenging task due to the complexity of the geomaterials in geotechnical engineering.

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Sleep assessment using accelerometry: Not all algorithms are equal

Sleep Research, EarlyView.
Abstract Study objectives Accelerometry devices are increasingly used to assess sleep. However, whether different algorithms provide consistent estimates remains uncertain. This study compared sleep parameters derived from two accelerometry‐based algorithms and a self‐reported sleep journal.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
