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 ...

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.

Soil precompression stress assessed from strain‐stress data in linear scale: The need for a physically based approach

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract State‐of‐the‐art models for soil compaction express soil strength by the so‐called precompression stress. The idea is to avoid stresses higher than those previously exposed to the soil. However, the quantification of soil precompression stress generally implies a problematic logarithmic transformation of the applied stress.

Interpretation of the Preconsolidation Stress in Soft Clay Using the One-Dimensional Consolidation Test

Journal of Marine Science and Engineering
This study explores interpretation methods for determining the preconsolidation stress from one-dimensional consolidation test results. Twelve reconstituted clay specimens with targeted preconsolidation stresses of 60 and 120 kPa were prepared using ...

Use of vertical drains and lime-cement stabilization to improve stability and reduce settlement of a high embankment on very sensitive, soft soil [PDF]

E3S Web of Conferences
This article presents a case-study of the design and construction of a 14 m high embankment for a highway construction project in mid-Norway. The ground consists of up to 30 m soft clay, with high sensitivity over bedrock.

How Does Heterogeneity Control Strain Localization Patterns in High‐Porosity Rocks?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract We aim to explore how heterogeneous porosity and grain size contribute to strain localization patterns in highly porous rocks based on phase‐field simulations. The strain localization patterns, including shear bands, dilatation bands, and compaction bands, are commonly observed in geological field studies and laboratory experiments.

Influence of Load Duration and Load Ratio on Preconsolidation Pressure

Journal of Engineering and Sustainable Development, 2008
Preconsolidation pressure is a very important parameter, which describes the stress history and affects the behavior of the cohesive soil in geotechnical engineering.
