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.

Subloading-overstress friction model
Nihon Kikai Gakkai ronbunshu, 2014 The subloading-friction model proposed formerly is capable of describing the transition from the static to the kinetic friction and the recovery of static friction, which leads to the negative rate-sensitivity, i.e.

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.

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.

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 ...

A viscoplasticity model with an enhanced control of the yield surface distortion
, 2012 A new model of metal viscoplasticity, which takes combined isotropic, kinematic, and distortional hardening into account, is presented. The basic modeling assumptions are illustrated using a new two-dimensional rheological analogy.
