Nihon Kikai Gakkai ronbunshu, 2016 This paper presents a re-formulation of the extended subloading surface model within the ‘unconventional plasticity’ concept applicable to cyclic loadings. The small strain theory is adopted in the model formulation.

Application of a Viscoelastic Model to Creep Settlement of High‐Fill Embankments
Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019 In order to predict the creep settlement of high‐fill embankments, the time‐dependent viscoelastic model of Poynting–Thomson (the standard linear solid) has been chosen to represent the creep behavior of soils. In the present study, the hereditary integral was applied to calculate the strain while the load increase is varied with time.

Unified Description of Elastoplastic Deformation of Solids : from Subloading Surface Concept to Tangential Plasticity [PDF]
The subloading surface model is based on the natural postulate that the plastic strain rate develops as the stress approaches the yield surface. Then, it is capable of describing rigorously the rate-independent/dependent elastoplastic deformation in ...

Accurate prediction of spring-back phenomenon by subloading surface mode [PDF]
, 2019 The subloading surface model possesses the distinguished capability to describe the plastic strain rate for the rate of stress inside the yield surface accurately and the stresscontrolling function to pull-back the stress to the yield surface even when ...

Analysis of Springback Behaviour in Micro Flexible Rolling of Crystalline Materials
Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018 This paper presents a constitutive modelling of the polycrystalline thin metal strip under a state of combined loading in microflexible rolling. The concept of grained inhomogeneity is incorporated into the classic Chaboche hardening model that accounts for the Bauschinger effect, in order to provide more precise description and analysis of the ...

Cyclic plasticity model for fatigue with softening behaviour below macroscopic yielding
Materials & Design, 2019 Experimental observations have evidenced the insufficiency of yield surface definition via monotonic loading to guarantee adequate description of material behaviour under fatigue tests.

Unified Description of the Mechanical Properties of Typical Marine Soil and Its Application
Shock and Vibration, Volume 2017, Issue 1, 2017., 2017 This study employed a modified elastoplastic constitutive model that can systematically describe the monotonic and cyclic mechanical behaviors of typical marine soils combining the subloading, normal, and superloading yield surfaces, in the seismic response analysis of three‐dimensional (3D) marine site.

A Mathematical Approach to Establishing Constitutive Models for Geomaterials
Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013 The mathematical foundation of the traditional elastoplastic constitutive theory for geomaterials is presented from the mathematical point of view, that is, the expression of stress‐strain relationship in principal stress/strain space being transformed to the expression in six‐dimensional space.
