Numerical study of a welded plate instability using the subloading surface model
Marine Structures, 2017Abstract 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 numerical study of the return mapping application for the subloading surface model
Engineering Computations, 2018Purpose 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 ...

Extended Subloading Surface Model
2014As 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

A critical state subloading surface model of sands with shear hardening
Journal of Central South University of Technology, 2008Based 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.

Elastoplastic Constitutive Model with a Subloading Surface
1986While the subloading surface model seems most reasonable among a lot of elastoplastic constitutive models proposed in the past, there exists a mathematical incompleteness in the past formulations of this model. The mathematically exact formulation of this model would be provided in this paper, formulating a reasonable translation rule of the center of ...

Unconventional Elastoplasticity Model: Subloading Surface Model
2009Elastoplastic 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.

A Corotational Elastoplastic Formulation With Subloading Surface Model for Hardening Materials
Volume 1, 2004In this paper a corotational constitutive model for the large elastoplastic deformation of hardening materials using subloading surface model is formulated. This formulation is obtained by refining the large deformation theory of Naghdabadi and Saidi (2002) adopting the corotational logarithmic (Hencky) strain rate tensor and incorporating it into the ...
