Experimental and numerical study of globe valve housing
(Savez hemijskih inženjera, Beograd, 2017)
Complex structure experimental analysis has always been a huge challenge for researchers. Conventional experimental methods (e.g., strain gauges) give only limited data sets regarding measurement on critical areas with ...
Rapid evaluation of maintenance process using statistical process control and simulation
(Daaam International Vienna, Vienna, 2018)
There are successful and less successful maintenance systems (MS). As a dynamic category, the success of the maintenance function must be taken into consideration both for the present day and the future. This is the reason ...
Analysis of strain distribution in overmatching V groove weld using digital image correlation
(Elsevier Science Bv, Amsterdam, 2018)
Welded joints are treated as critical sites when constructing and calculating welded structures due to inhomogeneity and anisotropy of materials at the welded joint site. Because of the change in the geometry of the elements, ...
Effect of temperature and exploitation time on tensile properties and plain strain fracture toughness, K-Ic, in a welded joint
(Elsevier Science Bv, Amsterdam, 2018)
Effect of temperature and exploitation time on resistance to brittle fracture of welded joint constituents of new and 40 years exploited low-alloyed Cr-Mo steel A-387 Gr. B has been analysed. The plane strain fracture ...
Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...
Non-homogeneity effect in the spherical shell by using seth's theory
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents nonlinear deformation behaviour of non-homogeneous spherical shell examined under pressure by using Seth's transition theory. It has been seen that for increased material compressibility in thickness ...
Primarna i sekundarna regulacija snage na blokovima tent B1 i B2 promenom protoka napojne vode kroz dodatni ekonomajzer
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2017)
Na parnim kotlovima blokova B1 i B2 Termoelektrane 'Nikola Tesla B' je tokom prve faze kapitalnog remonta ugrađen dodatni ekonomajzer, sledstveno 2012. i 2016. godine. Dodatni ekonomajzer se napaja vodom pomoću posebne ...
Influence of temperature and exploitation period on fatigue crack growth parameters in different regions of welded joints
(Gruppo Italiano Frattura, 2016)
The influence of exploitation period and temperature on the fatigue crack growth parameters in different regions of a welded joint is analysed for new and exploited low-alloyed Cr-Mo steel A-387 Gr. B. The parent metal is ...
Numerical Simulation of Fatigue Crack Growth in Hip Implants
(Elsevier Science Bv, Amsterdam, 2016)
In this paper numerical analysis of hip replacement implant behaviour from a fracture mechanics perspective is presented. It is necessary to understand the fatigue crack initiation and propagation characteristics in order ...
Welding safety by using a new model of welders' recertification in the oil and gas industry
(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents a solution applied for determining the quality of the welding process in oil and gas industrial plants, as well as reliable verification of professional qualification of welding personnel. By applying ...
