Abstract: In this paper, the sedimentation behavior of two kaolinite samples with distinct fabric associations is characterized using mechanical and electromagnetic wave-based techniques. The two different fabric formations, the ...

Abstract: Sands age and their engineering properties often improve significantly during performance life cycles and are of practical interest to engineers. Although various hypothesized aging mechanisms have been proposed, experimental ...

Abstract: This study investigates the aging effects on the small-strain shear modulus and damping ratio of sands and offers explanations for the measured results based on the concept of contact-force homogenization. Resonant column ...

Abstract: Nonlinear, dynamic coupling effects and the manifestation of stochastic resonance are explored in the context of frictional geomaterials. The first experiment is designed to study a single interface between two mineral ...

Abstract: In this study, aging in dry, clean sand induced by contact creep is investigated through numerical simulations using the discrete element method. Simulation results demonstrate that contact creep initiates the redistribution ...

Abstract: This paper examines and reports on two new methods, i.e., the Stockwell transform based (ST) method and self-healing cross-correlation (SC) method, in determining the S-wave arrival time for bender element tests, ...
