An EVP Double‐Yield Nonstationary Flow Surface Model for Soft Clay

open access: yesAdvances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
According to experimental findings, soft clay has compression and shear creep. The goal of the study is to develop an elastic‐viscoplastic (EVP) model for the viscous behavior of soft clay. The new EVP model is deduced from the associated flow rule, Yin’s double‐yield surface theory, and the critical state soil mechanics. The nonstationary flow surface

Anisotropic subloading surface Cam‐clay plasticity model with rotational hardening: Deformation gradient‐based formulation for finite strain

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 45, Issue 16, Page 2321-2370, November 2021., 2021
Abstract This study is aimed at developing an anisotropic elastoplastic constitutive model for geomaterials at finite strain and its stress calculation algorithm based on the fully implicit return‐mapping scheme. The Cam‐clay plasticity model is adopted as a specific prototype model of geomaterials.

Reloading in barodesy employing the asymptotic state boundary surface

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 45, Issue 14, Page 2113-2129, 10 October 2021., 2021
Abstract The reloading behaviour of the soil is dominated by effects of the recent deformation history as well as by the overall stress history, indicated by overconsolidation. The stiffness of an overconsolidated soil is higher than the stiffness of normally consolidated soil.

Constitutive Modelling of Temperature-Dependent Behaviour of Soft Rocks with Fractional-Order Flow Rule

open access: yesApplied Sciences, 2022
This paper regards soft rock as a heavily overconsolidated clay and proposes a new fractional elastoplastic model to describe its temperature-dependent mechanical behaviour.

Field Measurement and Numerical Simulation of Train‐Induced Vibration from a Metro Tunnel in Soft Deposits

open access: yesAdvances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Train‐induced vibration is increasingly attracting people’s concern nowadays. In the coastal areas, many metro tunnels are built in the soft deposits, so the train‐induced vibration effect is more serious. Nevertheless, the existing research studies mainly focus on the dynamic responses in the tunnel or on the ground surface while vibration ...

The Constitutive Model of Rockfill Based on Property‐Dependent Plastic Potential Theory for Geomaterials

open access: yesAdvances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
To better control the strength and deformation of the roadbed, a constitutive model of rockfill was established based on property‐dependent plastic potential theory for geomaterials. The effect of the particle gradation on the anisotropy was described in the model.

A thermodynamic-based model for modeling thermo-elastoplastic behaviors of saturated clayey soils considering bound water dehydration

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
The non-isothermal deformation of soft mudrocks or clay soils is one of the most critical issues in energy and environmental related geotechnics. Clay-related geomaterials hold complex microstructure and mineral composition, which brings difficulty in ...
