Mechanisms and morphologies of cavitation damage of NN 70 steel
(SERBIAN SOCIETY OF CORROSION AND MATERIALS PROTECTION (UISKOZAM), 2021)
Broken test tubes for low-cycle fatigue testing of Nionicral 70 (NN-70) parent material (PM) steel
and simulated heat-affected zones (SHAZ) were used to produce samples for cavitation resistance
testing. Ultrasonic ...
Some Aspects of Pile Testing Using Dynamic Load Test (DLT)
(Savez građevinskih inženjera Srbije SGIS, 2021)
The paper presents typical examples of pile load tests with a specific analysis of results, whereby the test methodology relies on existing ASTM standards, own knowledge and experience. The pile tests were conducted using ...
Corrosion protection of ship structures / Zaštita od korozije brodskih konstrukcija
(Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2021)
Hull maintenance is one of the most important aspect in ships lifetime. Ship maintenance represents
prevention of ship system failures, dealing with them and extending ships lifetime. Corrosion has
been a common cause ...
High strength low alloy steels impact toughness assessment at different test temperatures
(University of Banja Luka, Faculty of Mechanical Engineering, Banja Luka, Republika Srpska, 2021)
In many production processes, as well as in the exploitation of machine components and structures,
materials are exposed to impact loads. In structures made of welded joints of high strength low‐alloy
steels with their ...
Properties of concrete kerbs with recycled aggregate from precast elements
(ZAG, Ljubljana, 2021)
The paper presents the possibility of using recycled aggregate from precast concrete paving elements
and kerbs in the production of concrete kerb units. Experimental work included several types of concrete consistency
class ...
Repair of shaft and ventilation ring vanes damages of the generator of the hydroelectric generating set at the hydro power plant
(Savez energetičara, 2020)
Hydro power plant ’Pirot’, which was built in 1990, is
an accumulation-derivative power plant, which consists of 2
above-ground vertical hydroelectric generating sets that contain
Francis turbines with nominal power of ...
Welded Joints Integrity of the Pressure Vessels Pipes Made of Hot Rolled Fine-Grained Steel
(Savez energetičara, 2021)
This paper contains results of tests performed in order
to determine mechanical properties of steel P460NL1, meant for
production of pressure vessels. Arc welding of samples from
which the specimens were taken was carried ...
Effect of temperature and specimen orientation on Charpy impact toughness
(Elsevier, 2022)
Steel grade 14MoV6 3 is used for manufacturing of boilers and steam pipelines designed for steam temperatures up to 560°C. This paper presents the experimental analysis which included impact toughness test. The analysis ...
Lamellar Tearing of Parent Material and Degradation of Welded Joints at Vital Welded Structures
(Savez energetičara, 2021)
Vertical Kaplan turbines, manufactured in Russia, are
installed in 6 hydroelectric generating units at ‘Djerdap 1’, with
nominal power of 176 MW each. Because of the structural
solution and inability of performing ...
Modeling of Damping Effects in Soil – Structure Interaction in the Pushover Analysis
(1st Croatian Conference on Earthquake Engineering, Zagreb, Croatia, 2021)
The paper shows aspects of damping modelling in nonlinear static pushover analysis (NSPA) of structures through systematization of damping types and formed flow diagram, depending on the type of applied target displacement ...
