Control algorithm applied on the diesel engine
(VDI Verein Deutscher Ingenieure, 2014)
Material characterization of the main steam gate valve made of X20CrMoV 12.1 steel after long term service
(Elsevier Science Bv, Amsterdam, 2014)
Martensitic steel X20CrMo12.1 has been extensively used within the last few decades as a material for tubing systems and pipelines in thermal power plants (TPP). Long term behavior of this steel is very well known and ...
Fracture mechanics analysis of damaged turbine rotor discs using finite element method
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents evaluation fracture mechanics parameters in low pressure turbine components. Critical locations such as keyway and dovetail area are experiencing stress concentration leading to crack initiation. Stress ...
The combined method for uncertainty evaluation in electromagnetic radiation measurement
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Electromagnetic radiation of all frequencies represents one of the most common and fastest growing environmental influence. All populations are now exposed to varying degrees of electromagnetic radiation and the levels ...
Procena integriteta zavarenih cevi / Assessment of the integrity of welded pipes
(Inženjersko društvo za koroziju, Beograd, 2014)
Predmet rada je analiza integriteta zavarenih cevi izrađenih od čelika API J55 visokofrekventnim kontaktnim zavarivanjem (VF). Eksperimentalna ispitivanja mehaničkih osobina osnovnog materijala su izvršena na cevima povučenim ...
The failure analysis of the star-separator of an aircraft cannon
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper analyzes the causes of fracture of the double pipe aerial cannon stellate starseparator, which occurred during the fighting plane mission. The linear finite element method (FEM) is used to determine the stresses ...
Numerical modelling of crack propagation in friction stir welded joint made of aluminium alloy
(Elsevier Science Bv, Amsterdam, 2014)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded (FSW) joints has been numerically modelled. Crack propagation in unstiffened part of the structure between two ...
Projektovanje unutrašnjeg prostora putničkog vozila / Designing interior space for drivers of passenger vehicle
(Savez inženjera i tehničara Srbije, Beograd, 2014)
U radu je dat pregled naših prethodnih istraživanja uz dodatna unapređenja, tako da je dokazana hipoteza da putničko vozilo još uvek nije ergonomski prilagođeno čoveku u dovoljnoj meri, posebno u delu unutrašnjeg prostora ...
Radiative heat exchange inside the pulverized lignite fired furnace for the gray radiative properties with thermal equilibrium between phases
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2014)
The objective of the research was to find if an agreement of the results of a numerical investigation with experimental data could be achieved considering the two-phase medium in thermal equilibrium. Influence of the gray ...
Effect of Exploitation Conditions and Flaw Geometry on the Load Carrying Capacity of Casing Pipes for Oil Drilling Rigs
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The subject of this work is examination of API J55 steel casing pipes manufactured by high frequency (HF) contact welding. Since the pipes were withdrawn after about 70 000 hours of service in an oil drilling rig, the ...
