A unified model for clays and sands, referred to as CSUH model, is proposed. The CSUH
model develops the following aspects based on the unified hardening (UH) model:(a) a …

The research development of rockfill materials (RFM) was investigated by a series of large-
scale triaxial tests. It is observed that confining pressure and particle breakage play …

A new three-dimensional (3D) elastoviscoplastic (EVP) constitutive model for both normally
consolidated and overconsolidated clays is presented. In developing the new model, first the …

Density and pressure have great influences on the strength and stress-strain behaviors of
rockfill material. A series of triaxial compression tests were conducted for Tacheng rockfill …

The critical state line of Tacheng rockfill material (TRM) was described by a pressure-power
function. A simple bounding-surface plasticity model, combining the dilatancy stress ratio …

This paper proposes an anisotropic plasticity model to address the effect of consolidation
conditions on the responses of soils within the framework of the anisotropic critical state …

A unified critical state surface for gravels considering the effect of initial grading and particle
breakage was proposed in Part I based on the test results of large-scale triaxial compression …

A bounding surface model is formulated to simulate the behavior of clays that are subject to
an anisotropic consolidation stress history. Conventional rotational hardening is revisited …

This work presents an upgraded one-dimensional (1D) nonlinear rheological system of soft
ground consolidation. In the system, the boundaries are characterized by the time …

In this paper, by introducing a new yielding mechanism based on the widely acknowledged
double-structure theory, the original UH model for unsaturated soils is extended to capture …
