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

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.

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 ...

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.
