Construction and application of coal permeability model in reverse fault area
Meikuang Anquan, 2023 The superposition of tectonic stress and geostress in the reverse fault area, and the mechanical characteristics formed by compressive stress lead to gas accumulation, change of coal permeability, and easy to cause abnormal gas emission during mining ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Advanced Engineering Materials, EarlyView.Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Reverse order law for the group inverses
Journal of Mathematical Analysis and Applications, 2011 The group inverse \(T^\#\) of an operator \(T\in B(H)\) is the unique element (if it exists) \(T^\#\in B(H)\) such that \(TT^\#=T^\#T, T^\#TT^\#=T^\#\) and \(T=TT^\#T\). Some necessary and sufficient conditions for the existence of group inverses for square matrices are given in [\textit{C.-G. Cao} and \textit{J.-Y. Li}, Electron. J. Linear Algebra 18,

Some results on matrix partial orderings and reverse order law
The Electronic Journal of Linear Algebra, 2010 Some results relating different matrix partial orderings and the reverse order law for the Moore-Penrose inverse and the group inverse are given. Special attention is paid when at least one of the two involved matrices is EP.

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.
