Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

A multi-scale based cohesive zone model for the analysis of thickness scaling effect in fiber bridging [PDF]

, 2017
A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever ...

Numerical Modeling of Hydrogen‐Assisted Cracking With Phase Field Regularized Cohesive Zone Model and Penalty‐Based Moving Hydrogen Boundary Condition

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1824-1844, May 2026.
ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.

Multiple Time‐Scale Homogenization of Coupled Corrosion‐Fatigue in Structural Concrete

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT Reinforced concrete structures exposed to chloride‐rich environments and cyclic mechanical loading experience simultaneous corrosion of steel reinforcement and fatigue‐induced concrete cracking, leading to complex, nonlinear degradation that cannot be accurately captured by conventional sequential analyses.

Quantifying Lattice–Crack–Electrochemical Transport Coupling for Durable, Fast‐Charging Battery Cathodes

Advanced Energy Materials, Volume 16, Issue 13, 1 April 2026.
This study establishes a quantitative lattice–crack–transport framework that mechanistically links microstructural fracture, Li+ bulk diffusion, and interfacial charge transfer in layered cathodes. It reveals that crack‐generated surfaces dominate apparent transport enhancement in polycrystalline materials, while downsized single‐crystal particles can ...
