An unsaturated soil is a three-phase material that is ubiquitous on the earth's surface. The
fully saturated and completely dry states are just two limiting conditions of an unsaturated …

This work reviews the transient two-phase flow in porous media with engineering
applications in Geotechnics. It initially overviews constitutive relationships, conventional …

The soil pore space is an arena for processes responsible for numerous critical soil
functions. We sampled 15 soil samples from 3 horizons (A, E, Bt) and performed a detailed X …

Hypoplasticity has been around for some thirty years now. Starting from the crazy and yet
brilliant idea of Dimitrios Kolymbas in 1980s, it matured in the first half of 1990s into a …

This paper presents a hysteretic water retention curve (WRC) and unsaturated hydraulic
conductivity model for deformable soils based on the change in pore-size distribution (PSD) …

A new rate-independent hypoplastic model for clays is developed. The model is based on
the recently proposed approach enabling explicit incorporation of the predefined asymptotic …

The paper presents an experimental and modelling approach for the soil-water retention
behaviour of two deformable soils. The objective is to investigate the physical mechanisms …

This state-of-the-art covers advances in the constitutive modelling, experimental
investigation and field measurement of suction for unsaturated soils. It consists of three …

SUMMARY A constitutive model, accounting for multiphase and multiscale coupling, is
proposed for the water retention domain and the stress–strain response of compacted …

A formalism for double structure hydromechanical coupled modelling of aggregated
unsaturated soils has been developed. Independent coupled hydromechanical models are …
