Constitutive Modelling of the Cyclic Response of Unsaturated Soils: A Discussion of the State‐of‐Art

Shock and Vibration, Volume 2024, Issue 1, 2024.
Site response analysis (SRA) is an important aspect of seismic design that considers the impact of local site conditions on the ground response during earthquakes and plays a key role in the design of structures that interact or are made with soil. Although previous studies have demonstrated that factors such as the degree of saturation influence the ...

Fully undrained cyclic loading simulation on unsaturated soils using an elastoplastic model for unsaturated soils

E3S Web of Conferences, 2016
Several researchers have reported that Bishop’s mean effective stress decreases in unsaturated soils under fully undrained cyclic loading conditions, and unsaturated soils are finally liquefied in a similar manner as saturated soils.

Finite element analysis of ballast layer deformation caused by wheel passing through a rail joint with a grid-type sleeper

Nihon Kikai Gakkai ronbunshu
We investigate the deformation behavior of the ballast layer under a grid-type sleeper, using the elastoplastic FEM with the extended subloading surface 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.

Elastoplastic deformation analysis by return-mapping and consistent tangent modulus tensor based on subloading surface model (2st Report, Deformation analyses of machine elements)

Nihon Kikai Gakkai ronbunshu, 2014
The implicit stress integration algorithm was devised in the first report by formulating the return-mapping based on the cutting-plane projection and the consistent tangent modulus tensor due to the numerical method for the subloading surface model.

Evaluation of the horizontal load-carrying capacity of a thin steel bridge pier by means of the Damage Subloading Surface model

MATEC Web of Conferences, 2018
The evaluation of the load-carrying capacity of a structure is an important aspect of the structural design. In particular, large seismic events can significantly compromise the performances of structures, or parts of them, due to the formation and ...

Triple-shear Subloading Surface Hardening Model for Over-consolidated Unsaturated Clays

工程科学与技术
The Bishop stress variable method and the Fredlund stress variable method are applied to the triple-shear strength criterion to derive two triple-shear failure stress ratios and the related triple-shear yield surface equations for unsaturated clays under

Generalized subloading surface model with tangential stress rate effect

Journal of applied mechanics, 2005
The traditional elastoplastic constitutive equation, which is inde- pendent of the stress rate component tangential to the yield surface predicts an unrealistically stiff mechanical response for the nonproportional loading proc- ess in which the stress rate has a component tangential to the yield surface.

Seismic response analysis by subloading surface model

, 2015
A lot of disaster by liquefaction have been reported in area along the shore of Japan. In particular, liquefaction has occurred in the wide area in the Great East Japan Earthquake of 2011. Various approaches for the liquefaction analysis have been proposed up to present.
