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 ...
Experimental determination and numerical validation of the critical value of the J-integral ofa low carbon microalloyed steel for elevated temperature application
(VIII INTERNATIONAL CONGRESS ENGINEERING, ENVIRONMENT AND MATERIALS IN PROCESS INDUSTRY EEM 2023, 2023)
To evaluate the behavior of a homogeneous material in the presence of a crack-type defect, the
value of the critical stress-intensity factor, KIc, was determined as a measure of the fracture
toughness of the tested steel ...

Svojstva teškog SCC sa letećim pepelom
(XXVIII Kongres DIMK i IX Kongres SIGP sa međunarodnim simpozijumom o istraživanjima i primeni savremenih dostignuća u građevinarstvu u oblasti materijala i konstrukcija – Zbornik radova, 2022)
Leteći pepeo je visoko efikasan mineralni aditiv čija se uloga ogleda u poboljšanju mikrostrukture, čvrstoće i izdržljivosti kompozitnih građevinskih materijala kao što je samozbijajući beton (SCC). Referentni SCC je ...
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 ...
