Increased hydraulic resistance in tubes of once-through boiler due to fouling: a case study of 650 MWe ligite fired unit
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2022)
The analysis of pressure changes in water and steam flow along the entire once-through steam
boiler tube system at the 650 MWe lignite fired Unit was carried out after the long operational period
of almost 30 years ...
Structural Integrity Analysis of a Kaplan Turbine Cover
(Elsevier Science Bv, Amsterdam, 2022)
During recent revitalization of Kaplan turbine aggregate made of structural steel St 3 (GOST standard), experimental investigation was performed. Base metal and welded joints were tested by non-destructive methods (NDT), ...
Advanced Procedure for Making Vibro Motor Coupling of Basket Crusher by Welding and Plasma Cutting

The aim of this paper was to improve the technological procedure, operations and construction of the vibro-motor coupling of the crusher bucket from steel grade C45. The work defines important materials, approaches and ...
Influence of printing parameters on the eligibility of plane-strain fracture toughness results for PLA polymer
(Elsevier B.V., 2022)
The majority of manufacturers of polymer filaments for FDM technology rely their datasheets only on tensile tests, so their documentation usually lacks any data concerning fracture mechanics parameters. Having in mind the ...
Start-Up Community and the Acceleration Services in the Danube Macro-Region: Cases of Austria, Bosnia and Herzegovina, Hungary and Slovenia
(Springer Science and Business Media Deutschland GmbH, 2022)
This paper investigates the supply (access to finance) and demand (innovation-driven SMEs and talent communities) perspectives in the Danube macro-region (DMR). The purpose of this the empirical analysis is to identify ...
Comparison of Tensile Properties of Carbon/Epoxy Composite Materials with Different Fiber Orientation Using Digital Image Correlation
(Springer Science and Business Media Deutschland GmbH, 2022)
Due to its remarkable qualities, carbon fiber epoxy composite sandwich panels are used in a variety of engineering applications. The goal of this research is to use tensile testing and a full-field non-contact 3D Digital ...
Crack path direction in plane-strain fracture toughness assessment tests of quasi-brittle PLA polymer and ductile PLA-X composite
(Elsevier BV, 2022)
Plane-strain fracture toughness is one of the main parameters in linear elastic fracture mechanics and its purpose is to show the material capability to withstand load while having a defect. Main validity aspect for such ...
Analysis of fatigue behaviour of a bridge welded structure
(Elsevier Science Bv, Amsterdam, 2022)
Results of extensive experiments involving the fatigue behaviour of welded structures which are a part of the "Gazela" bridge in Belgrade, Serbia, are presented in this paper. After non-destructive testing of these structures, ...
Stress Corrosion Crack Growth Simulation by the Finite Element Method
(Springer Science and Business Media Deutschland GmbH, 2022)
Stress corrosion crack growth in mild steel was investigated by using the finite element simulation method. A model simulating crack growth considered an edge crack located on the metal surface, under tensile remote stress ...
