One-Dimensional Large-Strain Nonlinear Consolidation of Overconsolidated Clays with a Threshold Hydraulic Gradient

Advances in Civil Engineering, 2018
The existence of the threshold hydraulic gradient in clays under a low hydraulic gradient has been recognized by many studies. Meanwhile, most nature clays to some extent exist in an overconsolidated state more or less.

Laboratory and field determination of preconsolidation pressures at Gloucester

Canadian Geotechnical Journal, 1983
In recent literature several special test methods have been proposed to measure the preconsolidation pressure of a compressible clay soil. Five methods, in addition to the conventional oedometer test, were applied to the marine clays from the Gloucester test site.

Simulation‐Based Nonlinear Site Amplification Models for Western United States

Earthquake Spectra, Volume 42, Issue 4, November 2026.
This article presents one of the first nonlinear (NL) site amplification models relative to VS30 of 800 m/s for the Western United States (WUS) for both the smoothed effective amplitude spectrum (EAS), described as the orientation‐independent horizontal‐component Fourier amplitude spectrum (FAS) of ground acceleration, and the response spectra (RS ...

An Anisotropic Constitutive Model for Crushable Geomaterials Based on Non‐Stationary Critical State Line Concept

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5919-5935, November 2026.
ABSTRACT In this paper, the dependencies of granular soil behaviour on particle crushing and fabric anisotropy are formulated within a novel model based on bounding surface plasticity theory enriched by the non‐stationary critical state line (NCSL) concept.

Compactação de solos cultivados com cana-de-açúcar: I -modelagem e quantificação da compactação adicional após as operações de colheita Compaction of soils cultivated with sugarcane: I - modeling and quantification of the additional soil compaction after harvest operations

Engenharia Agrícola, 2010
A colheita mecanizada da cana-de-açúcar, quando realizada em épocas da safra em que o solo se encontra com conteúdos inadequados de água, tem sido responsável pela compactação do solo e a redução da produtividade nos ciclos posteriores da cultura.

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

Polymer Composites, Volume 47, Issue 19, Page 17076-17090, 10 October 2026.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

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

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.
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 ...
