An Improved True Triaxial Hoek–Brown Strength Criterion

工程科学与技术, 2023
Hoek–Brown strength criterion has been widely used in rock and rock mechanics analysis, rock slope stability analysis, rock tunnel design, and other fields, but the conventional Hoek–Brown strength criterion does not consider the influence of ...

A Chemical Damage Creep Model of Rock Considering the Influence of Triaxial Stress

, 2022
In order to accurately describe the characteristics of each stage of rock creep behavior under the combined action of acid environment and true triaxial stress, based on damage mechanics, chemical damage is connected with elastic modulus; thus, the ...

Optimum Cross‐Sections for Wurtzite‐Structure Nanowires From Analytic Thermodynamic and Crystallographic Arguments

Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.
Using the analytic cross‐section morphing of wurtzite nanowires to arbitrary shapes (König, Bian, Fu, and Smith, Adv. Theo. Simul. 2025, 8 2400951), the cross‐section shape with the maximum number of nanowire‐internal bonds per nanowire atom is derived, representing the most stable intrinsic crystalline form (structural‐thermodynamic optimum).

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 465-481, June 2026.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Creep: time‐dependent brittle deformation in rocks

, 2009
The characterization of time‐dependent brittle rock deformation is fundamental to understanding the long‐term evolution and dynamics of the Earth’s crust. The chemical influence of pore water promotes time‐dependent deformation through stress corrosion
