On modeling mixed hardening in computational plasticity [PDF]

open access: yesComputers & Structures, 2004
Abstract We address herein the calculation of Prager’s hardening parameter in computational plasticity when mixed hardening is considered. We consider two approaches to evaluate the mixed hardening response; namely, based on splitting the plastic strains and based on splitting the plastic modulus.

A Grid of Relativistic, non-LTE Accretion Disk Models for Spectral Fitting of Black Hole Binaries [PDF]

open access: yes, 2006
Self-consistent vertical structure models together with non-LTE radiative transfer should produce spectra from accretion disks around black holes which differ from multitemperature blackbodies at levels which may be observed. High resolution, high signal-

Implicit yield function formulation for granular and rock-like materials [PDF]

open access: yes, 2014
The constitutive modelling of granular, porous and quasi-brittle materials is based on yield (or damage) functions, which may exhibit features (for instance, lack of convexity, or branches where the values go to infinity, or false elastic domains ...

Beam element for large displacement analysis of elasto-plastic frames

open access: yesVietnam Journal of Mechanics, 2004
The present paper develops a non-linear beam element for analysis of elastoplastic frames under large displacements. The finite element formulations are derived by using the co-rotational approach and expression of the virtual work. The Gauss quadrature
