On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Comparison of modelling approaches for liquid fluidized beds

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

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

Energy evolution‐based damage quantification and failure prediction of fault zone tunnel lining concrete: A novel acoustic emission–strain energy coupling approach

Deep Underground Science and Engineering, EarlyView.
This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...
