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 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, ...
Suitability of Split Box Direct Tension Testing for Measuring Tensile Strength of Regolith Simulants
Publisher: American Society of Civil Engineers
Abstract: Under low effective stress conditions, the often-neglected soil tensile strength may significantly influence the behavior of lunar and Martian regoliths. Therefore, regoliths’ tensile strength in extraterrestrial environments ...
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 ...
