The subloading surface model fulfills the mechanical requirements for constitutive
equations, ie the continuity condition, the smoothness condition and the work rate stiffness …

This paper is concerned with a mathematical description of the undrained response of
partially saturated soils having a continuous liquid phase (water) and a gas in the form of …

The main focus in this work is on the assessment of bearing capacity of a shallow foundation
in an inherently anisotropic particulate medium. Both the experimental and numerical …

In this paper, we present a novel framework for solving boundary and initial-value problems
involving multiphase granular soils under monotonic, cyclic, and dynamic loads. To achieve …

The convexity of a yield/failure locus in the octahedral (π) plane is examined using an
appropriate analytical criterion. Various π-plane generalizations, applicable to frictional …

Accurate prediction of shear band formation in geomaterials is crucial in the solution of
various stability problems in geotechnical engineering. The initiation of shear band is …

INTRODUCTION Liquefaction of sandy soils during earthquakes is a cause for concern as it
may lead to disastrous consequences, such as significant structural damage and loss of life …

As a modification of the deviatoric hardening plasticity model, a material state-dependent
model was proposed to simulate the response of unsaturated sand containing gas bubbles …

Abstract The concept of “Critical State” as originally envisaged [1] is extended to include the
influence of the third invariant of the stress deviation tensor. The concept of “Steady State of …

The classical deviatoric hardening models are capable of characterizing the mechanical
response of granular materials for a broad range of degrees of compaction. This work finds …
