Comparative analysis of printing parameters effect on mechanical properties of natural PLA and advanced PLA-X material
(Elsevier, Amsterdam, 2020)
FDM is a commercially widespread 3D printing technology which uses thermoplastic materials for building prototypes and functional parts. Most used materials in this technology are PLA (PolyLactic Acid) and ABS (Acrylonitrile ...
LIFE CYCLE ASSESSMENT OF MAIN BIOMASS SUPPLY CHAINS IN SERBIA - INITIAL EVALUATIONS
(Full Papers Proceeding of International Conference "Power Plants 2023", November 2023, Zlatibor Serbia, 2023)
In this paper, life cycle assessment (LCA) of two biomass supply chains models in the Republic of Serbia were carried out: LCA of the wood and LCA of the agricultural biomass. These models were developed by analyzing data ...
Cavitation erosion resistance of basalt
(The 7thInternational conference ʺCivil engineering – Science and practice", Kolašin, Montenegro, 10-14 March 2020, Proceedings, 2020)
The cavitation erosion resistance of the basalt samples from Vrelo, Kopaonik deposit was investigated. The cavitation erosion test was performed using an ultrasonic vibratory cavitation testing method in accordance to the ...
Repairing of cracks on tooth gear ring of a bucket-wheel excavator
(Elsevier B.V., 2023)
Bucket-wheel excavators are continuously working machines for removal of waste and useful materials in open-pit mines, mainly used for mining of lignite. The purpose of a tooth gear ring is to rotate the excavator using ...
Predicting fatigue crack growth in complex geometries using numerical methods
(Procedia Structural Integrity, 2023)
Fatigue cracks growth in three different wing spar geometries is simulated using xFEM, as the most suitable numerical method for this purpose. The goal of this analysis was to find out how crack paths affect number of ...
Dimensioning and assemblying of brazed aluminium heat exchanger for needs of agricultural process plants
(University of Belgrade - Faculty of Agriculture, 2023)
Heat exchangers used in agricultural processes are mainly manufactured by three technologies: brazed copper-brass, mechanically assembled aluminum and brazed aluminum. The appropriate choice depends on various criteria: ...
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 ...
Interdisciplinary RES integration models for supporting decarbonizing society projects
(10th IPMA Research Conference "Value co-creation in the project society", 2022)
This paper deals with problem solving process of renewable energy sources integration in society that strives to create new decarbonizing environment. New Energy Policy 2050 defines a number of development projects, within ...
UTILIZATION OF THE FLUE GAS WASTE HEAT BY THE LOW-PRESSURE ECONOMIZER AT 350 MWE LIGNITE-FIRED POWER PLANT
(Beograd : Društvo termičara Srbije, 2023)
Potential for the waste heat utilization in coal-fired thermal power plants that are in operation for a long period is reflected in an increased temperature of the flue gas at the exit of the regenerative air heater. After ...
Contribution to strategic project management for dams towards sustainability
