Multiscale Validation of the Applicability of Micromechanical Models for Asphalt Mixture
Advances in Materials Science and Engineering, 2015 Asphalt mixture is more complicated than other composite materials in terms of the higher volume fraction of aggregate particles and the viscoelastic property of asphalt matrix, which obviously affect the applicabilities of the micromechanical models ...

A micromechanical model for predicting tensile strength [PDF]
, 2007 A novel micromechanical model for predicting the failure of polymeric and ceramic matrices under an applied global tensile loading is presented. The model is based on a Weibull statistical type of approach and incorporates eleven different variables to ...

Deep Underground Science and Engineering, EarlyView.Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

Deep Underground Science and Engineering, EarlyView.This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

A Biosourced and Self‐Healable Polymer Electrolyte for Potassium Batteries
EcoEnergy, EarlyView.A biosourced lignin‐filled gel polymer electrolyte combines suppressed crystallinity, high ionic conductivity, and UPy‐driven self‐healing for potassium batteries. The optimized formulation sustains long‐term cycling with 97.5% capacity retention after 1000 cycles and preserves electrochemical operation after intentional membrane damage.

A Cross-Scale Study of Data-Driven Micro-to-Macro Mechanical Heterogeneity in Sandstone
Applied SciencesTight sandstone gas development is largely governed by mineral composition and micromechanical heterogeneity. This study proposes a cross-scale method integrating these two factors to characterize macroscopic sandstone heterogeneity.
