Subloading Surface Model and Experimental Study of Coal Failure under Cyclic Loading
Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019 The fatigue damage of rock is an important factor affecting the stability of rock structure. In this paper, the mechanical response of coal under cyclic loading was studied. In order to accurately describe the deformation characteristics of coal under cyclic loading, an elastic‐plastic model of coal based on the theory of subloading surface was ...

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.

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.
