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

Advances 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

International 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

International 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.

Application of a Stress‐Fractional Model for Capturing the Stress‐Strain Behavior of Granular Soils

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Granular soils usually serve as the filler material in geotechnical engineering. This study presents the development and application of a stress‐fractional model for granular soils with different initial material states. To capture the plastic loading and flow behaviors, a subloading surface with the fractional stress gradient is used.

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

Advances 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

Advances 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.

Extension of subloading surface model for accurate prediction of elastoplastic deformation behavior of metals with cyclic softening

Nihon Kikai Gakkai ronbunshu, 2014
The subloading surface model has been formulated and applied to the prediction of cyclic loading behavior of metals. However, the existing formulation of this model is limited to metals exhibiting only the cyclic hardening.
