TL;DR: A review of the literature on shakedown problems of complex structures according to various hardening rules is given in this paper, where results of shakedown analyses for some complex structures are included.
84 citations
TL;DR: In this paper, thermal desorption spectroscopy and nanoindentation techniques were employed to elucidate the key differences in the hydrogen (H) charging methods and their consequences on the mechanical response of a low carbon steel.
83 citations
TL;DR: In this paper, the authors investigated the influence of precipitates on twinning mediated plasticity and the development of corresponding hardening models that account for twin-precipitate interactions using molecular dynamics simulations.

TL;DR: In this paper, the effects of cyclic hardening on crack tip plasticity and crack closure were investigated using abaqus finite element analysis and an empirical formula was provided to calculate the crack tip zone size under plane strain conditions in a cyclically hardening material.

TL;DR: In this article, surface carburizing of pure iron was investigated in aqueous solution, which consists of water, glycerin, and NH 4 Cl, for a very short period of time.
Abstract: In this study, surface carburizing of pure iron was investigated in aqueous solution, which consists of water, glycerin, and NH 4 Cl, for a very short period of time The formation of hard carbon-rich layer on the surface of pure iron was confirmed by XRD analysis SEM study combined with EDS showed the presence of carbon in the coated layer Moreover, RF-Glow Discharge Optical Emission Spectrometry (RFGDOES) presents only carbon diffusion into the base material Metallographic and SEM studies revealed that a uniform and compact carbon-rich layer was firmly sticking to the surface of the pure iron, and there was no crack observed between a carburized layer and a substrate The average thicknesses of carbon-saturated layers were changing from 12 μm for 10 s to 78 μm for 60 min The hardness of the carbon-rich layer on the substrate was 850 HV, while the hardness of the substrate was 150 HV
