New approach for computing damage parameters evolution in plastic damage model for concrete

open access: yesCase Studies in Construction Materials, 2022
The Damage Plastic Model is one of the most widespread models used to simulate the real behavior of concrete. The high reliability of this model could be attributed to its ability to take into consideration the elastic stiffness degradation induced by ...

Limit conditions on local failure of nuclear containment steels (Notched round-bar tensile tests for base metals and weld joint materials)

open access: yesNihon Kikai Gakkai ronbunshu, 2023
Tensile tests were conducted for notched round-bar specimens to acquire the limit conditions of local failure, which is ductile failure after large local deformation for three types of steel, SGV480, SPV490 and SGV410, for nuclear containment structures.

Two-state shear diagrams for complex fluids in shear flow [PDF]

open access: yes, 1999
The possible "phase diagrams'' for shear-induced phase transitions between two phases are collected. We consider shear-thickening and shear-thinning fluids, under conditions of both common strain rate and common stress in the two phases, and present the ...

P-T phase diagram of a holographic s+p model from Gauss-Bonnet gravity [PDF]

open access: yes, 2015
In this paper, we study the holographic s+p model in 5-dimensional bulk gravity with the Gauss-Bonnet term. We work in the probe limit and give the $\Delta$-T phase diagrams at three different values of the Gauss-Bonnet coefficient to show the effect of ...

STRESS ANALYSIS IN CYLINDRICAL SPECIMENS MADE FROM 34CrMo4 USING DIC

open access: yesActa Metallurgica Slovaca, 2014
The stress analysis using digital image correlation was carried out on cylindrical tensile specimens made from low carbon 34CrMo4 steel. The results obtained by conventional tensile test were compared with the results obtained by digital image ...

Railway wheel web fatigue design diagram

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Fatigue design of the railway wheel web is carried out in compliance with the JRIS J 0405 standard. However, this standard does not specify any evaluation method considering the thermal stress on the wheel web owing to tread braking.

Relations between loss angles in isotropic linear viscoelastic materials [PDF]

open access: yes, 1977
Starting from the relations between complex dynamic moduli simple diagrams are deduced connecting the locus of complex Poisson's ratiov* ≡v′ +iv″ in the complexv* plane with differences between various loss angles.
