Deformation Behavior of “Shirasu” and its prediction by the Subloading Surface Model
Soils and Foundations, 2002 ABSTRACT The description of the deformation behavior of Shirasu (volcanic sandy soil) by the elastoplastic constitutive equation is studied adopting a subloading surface model with rotational hardening. Also, test results for isotropic consolidation and triaxial compression with several lateral stresses under the drained and the undrained conditions ...

Numerical Analysis of Footing Settlement Problem by Subloading Surface Model
Soils and Foundations, 2009 This article addresses the numerical analysis of the load-settlement relation of footing on a soil ground by the finite difference method incorporating the subloading surface model. The subloading surface model is the elastoplastic constitutive model describing most pertinently the plastic strain rate due to the rate of stress inside the yield surface ...

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.

A subloading surface clay and sand model
, 2022 The mechanical response of natural soils is characterized by a narrow elastic domain, a smooth transition between elastic to elasto-plastic regime, and hysteretic behaviour during cyclic loading. These realistic features can be efficiently intro-duced into an existing constitutive model by reformulating it in the framework of subloading surface ...

Viscoplastic deformation analysis for spheroidal graphite cast iron by subloading-overstress model
Nihon Kikai Gakkai ronbunshu, 2020 The time-dependent elastoplastic deformation behavior, i.e. viscoplastic deformation behavior, is observed in solids and structures subjected to high temperature under monotonic and cyclic loadings.
