Neural network model for the condition assessment of hydro turbines
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
During regular operation, hydro turbine elements have complex operating conditions. In order to prevent major failures, among other common preventive measures, it is necessary to make a useful model of hydro turbine. ...
Analysis of Hertz contact stresses for metallic material with carbides
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
Hertz contact and the resulting stress-strain state arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental ...
Geometric optimization of shaft transition zone based on stress-strain analysis of nature inspired design
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
The presented research primarily considers with the geometric solutions that Nature has optimized. In the study presented in this paper, the nature inspired transition shapes are used in the research of innovative design ...
The effects of alloying elements on mechanical properties of NIOMOL 490K steel
(Twentieth Young Researchers’ Conference - Materials Science and Engineering: Programme and the Book of Abstracts, 2022)
This paper is to study the effect of alloying elements on mechanical properties of highstrength
low-alloy steel, NIOMOL 490K. This steel grade belongs to the class of
molybdenum microalloyed steels, in which microalloying ...
Application of coal combustion byproducts in self-compacting concrete: influence on flowability
(University of Belgrade, Technical Faculty in Bor, 2023)
Compared to traditional concrete, self-compacting concrete (SCC) demonstrates greater flowability, which is achieved by including an extra high percentage of ultra-fine particles. As a result, the required high paste content ...
Energy dispersive X-ray fluorescence in the investigation of the composition of historical mortars
(1st International Conference with Workshop, Science for Conservation of the Danube Limes Mortar Design for Conservation – Danube Roman Frontier 2000 Years After, Viminacium, Serbia, 2022)
Heavyweight Ultra-High-Performance Concrete with Micro-Reinforcement
(Serbian Ceramic Society Conference “Advanced Ceramic and Application XI – New frontiers in multifunctional material science and processing”, Book of Abstracts, Belgrade, Serbia, 2023)
The impacts of nano-silica addition, steel micro-reinforcement, and aggregate type on the mechanical properties and durability of ultra-high-performance concrete (UHPC) were studied. As aggregates, quartz and barite were ...
Possibility of Using Other Additives as Replacement for Air Entraining Admixture in Concrete
(Serbian Ceramic Society Conference - Advanced Ceramics and Applications X: New Frontiers in Multifunctional Material Science and Processing, Book of Abstracts, 2022)
Concrete in which the air entraining admixture was used can exhibit behavior which alternate from the ‘standard’ concrete behavior when employed in the structural design. The origin of this problem can be found in the ...
Impact of fine aggregate particle size and morphology on the early strengths of SCC
(International Congress Proceedings / Association of Structural Engineers of Serbia, 16. Congress, Aranđelovac, Serbia, 2022)
A comparative study of performances of self compacting concrete (SCC) with fly ash and limestone filler was conducted. The experimental program included the production of reference SCC designed with Portland cement, river ...
Influence of different types of fibers on flexural tensile strength
(Proceedings of the ASES International Symposium, Aranđelovac, Serbia, 2022)
The paper presents the influence of the application of different types of fibers in
concrete beams on the flexural tensile strength. All concrete beams were made of
the same component materials and composition, except ...
