Analysis of contact fatigue coupled with geometry and material nonlinearities by Theory of critical distances
(2nd Conference on Nonlinearity, Belgrade, 2022)
The contact fatigue is a localized phenomenon that occurs in highly
stressed local zone of the material under the loaded contact region and as such is
highly nonlinear problem. This phenomenon exists in almost all real ...
Experimental research of mechanical characteristics of railway vehicles safety coupling components
(International Conference of Experimental and Numerical Investigations and New Technologies CNN TECH 2021, Zlatibor, Serbia, 2021)
The coupling system provides a mechanical connection between European railway vehicles. Screw couplings are designed as a safety device in railway vehicles with coupling links and screw as two main components intended to ...
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 ...
Failure analysis of beam of unmanned aerial vehicle
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
The high level of worthiness of unmanned aerial vehicles (UAV), particularly in everyday life, is something that will be common thing in close future. The design solutions for UAV us subject of constant innovation, focused ...
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 ...
Lime mortars containing clays for the conservation of the Danube Limes
(International Congress Chemistry for Cultural Heritage 6th ChemCH Congress, Ravenna, Italy, 2022)
Overview of the new rulebook on testing fire resistance, external fire performances and reaction to fire in the Republic of Serbia
(THE 8th INTERNATIONAL CONFERENCE "CIVIL ENGINEERING – SCIENCE AND PRACTICE", GNP 2022, Proceedings, 2022)
The growing expansion of construction and import of new, as well as existing materials from around the world, has led to a large number of tests materials and elements of constructions in the Republic of Serbia. Most of ...
Influence of water/cement ratio on the properties of fresh SCC with fly ash addition
(Proceeding of the 8th International Conference "Civil engineering-science and practice" -GNP 2022, 2022)
Self-compacting concrete (SCC) exhibits increased flowability in comparison with the conventional vibrated concrete. This is most often achieved through the incorporation of high amounts of extra-fine particles (i.e. mineral ...
