Assessment of pressure vessel load capacity in the presence of cracks / Procena nosivosti posude pod pritiskom u prisustvu prsline
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
The paper illustrates the structural assessment of an investigated pressure vessel, made of low-alloyed high strength steel, with an external surface crack located on the shell wall. In order to assess the remaining strength ...
Production of rubber plasticizers based on waste PET: Techno-economical aspect / Sinteza plastifikatora iz otpadnog PET-a za primenu u gumenim proizvodima - tehno-ekonomska analiza
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Production of rubber plasticizers, based on waste poly(ethylene terephthalate) (PET), and economic effectiveness of developed technologies are presented and discussed. Waste PET glycolyzates, named diisononyl terephthalate(DINTP), ...
Solvatochromism of 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones / Solvatohromizam 5-(4-supstituisanih arilazo)-4-fenil-6-metil-3-cijano-2-piridona
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Eight 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones were synthesized by reaction of benzoylacetone and arendiazonium salt, followed by condensation with cyanoacetamide. Absorption spectra of all azo ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
Synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalysed by amino acids / Sinteza 4,6-dimetil-3-cijano-2-piridona katalizovana aminokiselinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In this work the synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalyzed by amino acids was studied. In the first part of the work, the optimization was carried out by varying the initial concentration of glycine, the molar ...
Effect of vibration on the variation of residual stresses and impact energy in butt-welded joints / Uticaj vibracija na promenu zaostalih napona i energije udara kod sučeono zavarenih spojeva
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a ...
Integrity assessment of reverse engineered ti-6al-4v eli total hip replacement implant
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
Total hip replacement implants are used as an artificial replacement for disfunctional hips in order to sustain joint movement. Chosen material and design of total hip replacement are the most influential factors for ...
Analysis of the effects of butt welded joints on a carrying capacity of a structure tank / Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In the present paper, after calculation using the Finite Element Method (FEM), stress distribution on the model of a part of the pressure-tank mantle without welded joints (WJ), with transversal WJ, longitudinal WJ and ...
Behaviour of nionikral-70 in low-cycle fatigue
(Society for Structural Integrity and Life, Institute for Material Testing, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
