RISThree-Dimensional Evaluation of Sand Particle Fracture Using Discrete-Element Method and Synchrotron Microcomputed Tomography Images
Publisher: ASCE
Abstract: Recent research showed that fracture of sand particles plays a significant role in determining the plastic bulk volumetric changes of granular materials under different loading conditions. One of the major tools used to ...
Influence of Particle Morphology on 3D Kinematic Behavior and Strain Localization of Sheared Sand
Publisher: American Society of Civil Engineers
Quantifying Morphology of Sands Using 3D Imaging
Publisher: American Society of Civil Engineers
Abstract: Particle morphology plays a significant role in influencing engineering behavior of granular materials. Surface texture, roundness, and sphericity represent distinct multiscale measures needed to fully describe particle ...
Discrepancy 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 ...
Micro Shear Bands: Precursor for Strain Localization in Sheared Granular Materials
Publisher: American Society of Civil Engineers
Abstract: Recent studies have shown that detection of the onset and evolution of micro shear bands (MSBs) in granular materials can be improved using measurements of the kinematic behavior of particles. Different methods such as the ...
