Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

A Method for Correcting Undrained Shear Strength for Sample Disturbance

Soils and Foundations, 1985
ABSTRACT In order to find out an appropriate method for correcting the undrained shear strength for sample disturbance, a series of triaxial compression tests is performed on mixed soil samples having wide range of plasticity index. Conditions of the ideal and perfect samples are brought to by the K0 consolidation and the shear stress release after ...

A Surrogate Model for Stability Assessment of Two‐Layered Cohesive Slopes

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4142-4163, July 2026.
ABSTRACT This paper introduces a novel surrogate model for rapid stability evaluation of two‐layered cohesive slopes under undrained conditions. The model eliminates the need for iterative calculations and slip surface searches, allowing for fast and accurate stability assessments without reliance on advanced numerical tools. The formulation is derived

Laboratory Study on Vallejo and Scovazzo’s Methods in Estimating the Rheology Parameters of Bentonite and Kaolinite Muds

Civil Engineering Dimension
The mud undrained shear strength and viscosity are the essential parameters in understanding the behavior of mudflow. One of the laboratory test methods to estimate the undrained shear strength and viscosity is Vallejo and Scovazzo’s cylinder strength ...

Undrained shear strength of Lisbon Miocene clay: a reappraisal based on triaxial and pressuremeter test results

SN Applied Sciences, 2021
Undrained shear strength plays a fundamental role on the behaviour of clays. In overconsolidated clays, this parameter is largely influenced by test conditions, namely consolidation stress.

Correlation of the Undrained Shear Strength

Nigerian Journal of Technology, 2012
This paper attempts to establish a relationship between the undrained strength and plasticity index of tropical clays. Its theoretical basis lies with the previous works of Skempton and Northey [1] and Atkinson and Bransby [2]. The data obtained from independent laboratory tests on so some clay samples sourced from several actual project locations in ...

Evaluation of the undrained shear strength of Busan clay

KSCE Journal of Civil Engineering, 2012
The current paper presents an estimation of the undrained shear strength (su) of Busan clay through a comparison of the results of field vane and laboratory shear test results at two sites in the Nakdong River Delta. The results indicate that because of fabric effects in the clay, determining the effective overburden stress (σν0′) and the field vane ...

Evolution of Pore Fluid Pressure in an Accretionary Outer Wedge Over Megathrust Earthquake Cycles: The Northern Cascadia Example

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

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 ...
