Tribological characterisation in dry sliding conditions of compocasted hybrid A356/SiCp/Grp composites with graphite macroparticles
(Springer London Ltd, London, 2019)
The influence of SiC microparticles reinforcement and graphite macroparticles addition on the friction and wear characteristics of A356 Al-Si alloys, produced by compocasting, has been assessed using a pin-on-disc tribometer. ...
Cavitation Wear of Basalt-Based Glass Ceramic
(MDPI, Basel, 2019)
This paper examines the possibility of using basalt-based glass ceramics for construction of structural parts of equipment in metallurgy and mining. An ultrasonic vibration method with a stationary sample pursuant to the ...
Multidisciplinary research method for designing and selection of bio-inspired profiles in the conceptual designing stage
(Springer Heidelberg, Heidelberg, 2021)
A multidisciplinary research method was employed with the intention to create a series of bio-inspired flattened airfoils, observe their aerodynamic characteristics, and analyse their applicability to small devices or to ...
Numerical simulation of tensile testing of pe 80 polymer specimens
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
The aim of this paper is to present the behaviour of specimens made of polyethylene material PE 80, subjected to tensile load until failure. Measurements of the temperature distribution have been done using the infrared ...
Fracture analysis of the pulley of a bucket wheel boom hoist system
(Polish Maintenance Soc, Lublin, 2016)
This paper presents the results of the pulley fracture analysis. Experimental investigations confirmed that the chemical composition and basic mechanical properties of the pulley material, except the impact energy at a ...
Best Practices of Biomass Energy Life Cycle Assessment and Possible Applications in Serbia
(Zagreb Univ, Fac Forestry, Zagreb, 2016)
This paper aims to highlight the advantages of using Life Cycle Assessment (or LCA) tool in energy sector for rational energy consumption, selection of green technologies and process optimization. Besides the definition ...
3D Digital Image Correlation Analysis of the Shrinkage Strain in Four Dual Cure Composite Cements
(Hindawi Ltd, London, 2019)
The introduction of resin-based cements and an adhesive-bonding system in daily dental practice has given the opportunity to increase the retention of previously conventional cemented restorations and the optimal results ...
Importance of on-time decision making in energy sector based on perspectives case study new stavalj project
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
Expression "Development conditions and perspectives" became important for numerous analyses in various industrial and social areas. Several strategic documents and studies in last two decades analysed projects with topics ...
CFD Calculation of Helicopter Tail Rotor Airloads for Fatigue Strength Experiments
(Asce-Amer Soc Civil Engineers, Reston, 2017)
This work focuses on defining loads and fatigue life estimation of helicopter tail rotor blades. The original metal construction of these blades was replaced with a new construction of blades made from composite materials. ...
Determination of bond strength between the hard-faced (HF) layer and the base material (BM) of forging dies
(Faculty of Metallurgy, 2016)
This paper points out complex working conditions of forging dies, which are the most frequent causes of their damage, and proposes suitable hard-facing repair procedures. The shear strength between the hard-faced layer and ...
