A numerical study of the return mapping application for the subloading surface model

Engineering Computations, 2018
Purpose Many practical problems in engineering require fast, accurate numerical results. In particular, in cyclic plasticity or fatigue simulations, the high number of loading cycles increases the computation effort and time. The purpose of this study is to show that the return mapping technique in the framework of unconventional plasticity theories ...

Subloading surface model in unconventional plasticity

International Journal of Solids and Structures, 1989
Abstract For engineering problems, the elastoplastic constitutive model has been required, which is applicable to the prediction of cyclic loading behavior for various stress/strain amplitudes. The subloading surface model has been proposed and developed in order to respond to this requirement.

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 ...

Cyclic Plasticity Model: Extended Subloading Surface Model

Lecture Notes in Applied and Computational Mechanics, 2009
The subloading surface model described in Chapter 7 would be the only pertinent unconventional model for the description of monotonic loading behavior but it cannot describe the cyclic loading behavior pertinently by the formulation itself shown therein, predicting the unrealistically large plastic strain accumulation because only elastic deformation ...

Extended Subloading Surface Model

2014
As was deliberated in Chapter 8, only the extended subloading surface model is capable of describing the cyclic loading behavior of materials pertinently. The explicit constitutive equation of this model is shown in this chapter. Then, this model will be applied to metals and soils, and their validities will be verified by comparisons with test data of

Numerical study of a welded plate instability using the subloading surface model

Marine Structures, 2017
Abstract Instability in structural components has been widely studied to understand the elastic and inelastic behaviors of materials because of the risks associated with sudden failure of components under equilibrium conditions. However, most studies have been performed for various monotonic load configurations without considering the instability as ...

A critical state subloading surface model of sands with shear hardening

Journal of Central South University of Technology, 2008
Based on the framework of critical state soil mechanics, a subloading surface plastic model for sand, being applicable to cyclic loading, was proposed. The model can be used to describe strain softening behaviour of sand under monotonic loading when the similarity-ratio equals to unity.

Unconventional Elastoplasticity Model: Subloading Surface Model

2009
Elastoplastic constitutive equations with the yield surface enclosing the elastic domain possess many limitations in the description of elastoplastic deformation, as explained in the last chapter. They are designated as the conventional model in Drucker’s (1988) classification of plasticity models.
