RISDiscrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
Publisher: ASCE
Abstract: The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ...
Influence of Micro- and Crystalline-Scale Properties on the Fracture of Silica Sand Particles Using 3D Finite-Element Analysis
Publisher: ASCE
Abstract: Particle fracture significantly influences the constitutive behavior of sands and impacts many geotechnical engineering applications, such as hydraulic fracturing, pile driving, blast loading, and stability of dams. When ...
Influence of Sand Morphology on Interparticle Force and Stress Transmission Using Three-Dimensional Discrete- and Finite-Element Methods
Publisher: ASCE
Abstract: In the last two decades, particle morphology has emerged as an essential and critical property for proper evaluation of the constitutive behavior of granular materials. When a mass of sand is loaded in a confined compression, ...
3D Dislocation Density–Based Crystal Plasticity Model for Rock Salt under Different Temperatures and Strain Rates
Publisher: ASCE
Abstract: Rock salt is a sedimentary rock found in nature as bedded or domal deposits due to evaporating inland seas or any enclosed bodies of saline water. Rock salt hosts caverns within the underground deposits that can potentially ...
3D Experimental Measurements of Evolution of Force Chains in Natural Silica Sand
Publisher: ASCE
Abstract: The mechanisms of force transmission in granular materials is a classic physics problem that has been addressed since the 19th century, when Heinrich Rudolf Hertz investigated the interaction between two similar objects ...
