In this study, a hypoplastic model is developed to describe the mechanical behaviors of
cemented sand under both monotonic and cyclic loading conditions. A state variable is …

The modeling of anisotropic sand has always been a challenging and prominent issue in
geotechnical constitutive research. This paper presents a hypoplastic constitutive model for …

We present a hypoplastic model for the granular material to account for the particle
breakage effect. The degree of particle breakage is expressed by a relative breakage ratio …

Depending on the characteristics of soil particles and external load, natural soils often
undergo particle breakage which may significantly influence their mechanical behavior. In …

Granular materials, such as rockfill materials and carbonate sand, exhibit complex
mechanical behavior, which is affected by particle breakage under elevated pressures. In …

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 …

We propose a hypoplastic model for granular soil using the memory surface notion to
consider the stress history. This paper aims to resolve the limitations of the hypoplastic …

We present a hypoplastic model to capture the mechanical responses of hydrate‐bearing
sands by incorporating hydrate saturation and grain breakage. In our model, a new …

Partially saturated soils are ubiquitous in natural environments but still pose significant
challenges for constitutive modeling. In this paper, a simple hypoplastic constitutive model …

Previous experimental tests on clays have confirmed the non-coincidence of principal strain
increments with principal stress axes even though the stress rate is colinear with the current …
