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 ...
Parameter programs for 3D modeling in the function of nondestructive testing and determination of the lifetime of pressure vessels
(UNIVERSITY OF EAST SARAJEVO FACULTY OF TECHNOLOGY, 2023)
Preparation for non-destructive testing (NDT), preparation of test reports, as well as control
calculation of a pressure vessel (PV) using the finite element method (FEM), with or without
identified irregularities, ...
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 ...
Some Aspects of Pile Testing Using Static Load Test (SLT)
(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 ...
Static-Dynamic Tests of Bearing Capacity of Wind Turbine Piles
(Comptes rendus de l’Académie bulgare des Sciences, 2022)
The paper presents the static load tests (SLT) and dynamic load tests (DLT) of the piles and numerical analyses of piles in interaction with the soil of wind turbines. Pile tests were conducted using the equipment with ...
3D Modeling in the Function of Cavitation Demage Testing at Hydropower Plants
(Savez energetičara, 2021)
Characteristics of composite materials based on polylactic acid (PLA) / Karakteristike kompozitnih materijala na bazi polilaktidne kiseline (PLA)
(Savez inženjera i tehničara Srbije, Beograd, 2023)
Polylactic acid (PLA) is aliphatic thermoplastic polyester. Composites based on PLA are biocompatible,
biodegradable and non-toxic, which are the main advantages of using such composites. Based on the
research results ...
