Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
Experimental and numerical investigations of the critical values of J-integral for the steel of steam pipelines
(Elsevier Science Bv, Amsterdam, 2018)
Steel grade 14MoV6-3 is a low-carbon microalloyed steel with addition of chromium and molybdenum. This grade is designed mainly for power industry applications, withstanding operating at elevated temperatures.In this paper, ...
Compressive Strength Improvements of Cement-Based Composites Achieved with Additional Milling of Metakaolin
(Springer, Dordrecht, 2018)
Kaolin from a Serbian deposit, having a high content of mica and quartz, disordered kaolinite and a high specific surface area, was used to prepare metakaolin (MK). The calcination at temperatures of 700 degrees C or 750 ...
Properties of the Cement-Based Composites with High Content of Metakaolin
(Springer, Dordrecht, 2018)
Environmental concerns and sustainable development require increased replacement of cement. Most of previous studies have shown that the compressive strength of cement-based composites is maximized with a 20% content of ...
Gas cylinder rupture induced by local corrosion damage
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
Commercial gas cylinders are common type of pressure vessels in many health care and technical facilities. Unexpected
failures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
Comprehensive approach to weld repair on elements of power transmission – case study for hydro turbine shaft
(Proceedings of the The 4th IIW South – East European Welding Congress, October, 10-13, 2018, Belgrade, 2018)
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 ...
Comparison and evaluation of recently reported methods for optimization of industrial drying regimes
(IOP Publishing Ltd, Bristol, 2018)
In our previous studies we have presented the calculation method along with the procedure for setting up the non isothermal drying regime. Even though this method is harmonized, with the theory of moisture migration during ...
In situ experimental determination of the heat transmittance of a building wall
(Građevinski fakultet Subotica, 2018)
In this paper, results of a long term experimental in-situ measurement of air
temperatures and heat fluxes trough a building wall surfaces, are presented. Indoor and
outdoor measurements were carried out simultaneously ...
Morphology of corrosion fatigue and stress corrosion cracks on low alloy steels
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
The fracture surface appearances are slowly changed through decade’s side by advantages in technology of steel production.
Basic requirements for cleaner steels and lower energy consumption during production induce that ...
Common failures in aluminothermic welding process and proposal for their prevention
(University of Zagreb, Faculty of Metallurgy, 2018)
Aluminothermic welding of rail is still a unique method for joining the rails because of its flexibility
and ease of performance, both during the reconstruction and construction of a new track, as well as
in the ongoing ...
