Modeling and experimental validation of bolt–grout bond–slip behavior for deep underground excavation support

Deep Underground Science and Engineering, EarlyView.
A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Overcoming Cell Fixture Challenges in High‐Pressure Operation of Solid‐State Batteries

Energy Science &Engineering, EarlyView.
Accurate application of high uniaxial pressure remains a limiting factor in large‐format solid‐state battery testing. A spring‐loaded fixture employing deflection‐based pressurization enables precise, homogeneous, and reproducible pressure application without expensive in‐fixture sensors, providing a robust framework for systematic investigation of ...

Influence of Strain Rate on the Strain Hardening Behavior of a Lean Duplex Stainless Steel

MetalMat, EarlyView.
The aim of this study was to examine how strain rate influences the compressive strain‐hardening behavior of a lean duplex stainless steel LDX 2101. Microstructural analysis using electron backscatter diffraction (EBSD) revealed a strain‐induced austenite‐to‐martensite transformation.

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...

Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

River Research and Applications, EarlyView.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed
