Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Experimental study on the stresses at the i-beam end-plate moment connection
(Institut za ispitivanje materijala, Beograd, 2019)
The paper deals with experimental study of the stresses at the bolted end-plate moment connection. The design parameters are adopted to include prying effects in joint. A stress level is obtained in the elements where the ...
Repair of cracks detected in cast components of vertical Kaplan turbine rotor hub
(Institut za ispitivanje materijala, Beograd, 2019)
During the revitalization of the hydroelectric generating station A4 at the hydro power plant 'Djerdap 1', all of its parts are subjected to non-destructive testing. Cracks are detected in cast part of generator rotor hub, ...
Analiza stanja vitalne čelične konstrukcije kabine rukovaoca rotornog bagera nakon havarije i sanacije / State analysis of the vital steel structure of the bucket-wheel reclaimer operators cabin after the breakdown and the rehabilitation
(Institut IMK "14. oktobar", Kruševac, 2019)
Na deponiji uglja termoelektrane "Nikola Tesla A" u Obrenovcu (Srbija), rade dva rotorna bagera interne oznake DU1 i DU2, koji su proizved francuske fabrike "Ameco" i kreću se po kružnoj stazi (tzv. polarna staza), uz ...
Activated flux tig welding of stainless-steel pipes
(Savez hemijskih inženjera, Beograd, 2019)
In this work, the presence of TiO2 nanoparticle-based activated flux combined with orbital welding of seamless thick-walled pipes of stainless steel and low-cycle pulse current was done, representing a novel combination ...
An analytical approach based on Green's function to thermal response factors for composite planar structure with experimental validation
(Elsevier Sci Ltd, Oxford, 2019)
The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Green's Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature ...
Thermal and Mechanical Behavior of Composite Mortars Containing Natural Sorptive Clays and Fly Ash
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Mineral additives are extensively applied as cement replacement materials in both construction concrete and mortar. Fly ash is one of the most commonly utilized additives which improve Theological properties, as well as ...
Novel Approach for Determination of Potentially Toxic Elements via ICP-OES in Aqueous Solutions of Building Materials with Industrial Byproduct Addition
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
New global tendencies for waste materials reusing in building materials are imposing the request for improved performances of chemical analysis methods and the improvements of matrices used. A new method for optical emission ...
Analiza postupka ocenjivanja životnog ciklusa opekarskih proizvoda
(Izgradnja, 2019)
Poznato je da se u proizvodnji opekarskih proizvoda koriste velike količine sirovina koje takođe uključuju visoku potrošnju energije što se negativno odražava na kvalitet životne sredine. Ocenjivanje životnog ciklusa (eng. ...
Feasibility Analysis for Repair of Large Diameter Hydro Turbine Shaft Based on Weldability Test and Welding Cycle Simulation
(Advanced Materials Research, 2019)
Turbine and generator rotors and shafts undergo high stresses during regular working life
and, from a safety and operational aspect, are the most significant components of a power
generation system. Depending on the ...
