Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Molecular Insights Into the Water Freezing on Kaolinite Surfaces: The Key Role of Surface Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Unfrozen water content is a key factor governing the physical properties of frozen soils, and variations in mineral surface properties play a critical role in determining this content. However, the fundamental physical mechanisms of how different mineral surfaces affect soil water freezing remain poorly understood.

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior

ChemistryOpen, EarlyView.
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...

Kaolinite Oxamyl Interactions

, 1980
Chemical Laboratories, D. S. College, Aligarh-202 001 Manuscript received 16 May 1979, accepted 25 August 1980 The adsorptive behaviour of oxamyl with H-, Na- and Ca- kaolinites was studied. The effect of time on adsorption showed that process was diffusion controlled. Kinetic studies showed that reaction was of first order. Maximum adsorption occurred
