A gradation-dependent hypoplastic model is developed to capture the mechanical
behaviours of crushable sands. First, a gradation evolution law is proposed to describe the …

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

We propose a constitutive model for both the solid-like and fluid-like behavior of granular
materials by decomposing the stress tensor into quasi-static and collisional components. A …

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 …

The impact of particle crushing and relative density on calcareous sand is substantial;
however, relevant studies, particularly in constitutive modelling, remain limited. To address …

In this paper, we report on cyclic hollow cylinder tests on Fujian sand and Nan**g sand
subjected to different loading frequencies. Depending on the loading frequencies we …

The presence of fines can significantly influence the mechanical behavior of soils. In this
study, a hypoplastic model is extended to simulate the stress-strain relationship of sand …

We propose a hypoplastic model to capture the short-term and long-term creep behavior of
granular material by incorporating grain breakage and wetting effect. In the proposed model …

We present a unified constitutive model for the solid-like and fluid-like behaviour of granular
materials by decomposing the stress rate tensor into frictional and collisional parts. An …

One of the main problems of carbonate sands is the fragile nature of particles and their
susceptibility to breakage. Carbonate sands are affected by volumetric strain even at low …
