Development and calculation of supporting structure for mining power equipment
(Institut za ispitivanje materijala, Beograd, 2021)
Development and calculation of the base supporting struc-ture used for mining equipment is the aim of the paper. The base structure is intended for the installation of electronic communication and power equipment and devices ...
Corrosion behaviour of AA2024 aluminium alloy in different tempers in NaCl solution and with the CeCl3 corrosion inhibitor
(Wiley-V C H Verlag Gmbh, Weinheim, 2020)
The paper analyses the corrosion behaviour of naturally and artificially aged AA2024 alloy in NaCl solution and in the presence of an environment-friendly corrosion inhibitor, CeCl3. On the basis of the values of polarisation ...
Engineering critical assessment of steel shell structure elements welded joints under high cycle fatigue
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Existing flaws in critical parts of structural elements may lead to failures of subassemblies and, in case of lack of redundancy, even to the entire structure collapse. Considering the case of cyclic loading - wind load ...
Numerical simulation of "Hall 1 of the Belgrade Fair"
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
This paper involves the analytical and numerical calculations of the the largest pre-stressed concrete free-standing structure in the world - the Dome of the "Hall 1 of the Belgrade Fair", designed by a well-known Serbian ...
Thermomechanical behavior of bio-fiber composite thermal insulation panels
(Elsevier Science Sa, Lausanne, 2020)
The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus x giganteus bio-fibers, mineral ...
Effect of laser shock peening with and without protective coating on the microstructure and mechanical properties of Ti-alloy
(Elsevier Sci Ltd, Oxford, 2020)
Owing to their good mechanical properties, titanium based alloys are used for machine parts and devices that operate in demanding regimes and environmental conditions. Laser shock peening (LSP) is an innovative technique ...
Experimental and numerical study of temperature field during hard-facing of different carbon steels
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
In this research the 3-D transient non-linear thermal analysis of the hard-facing process was performed by using the experimental testing and finite element method. Testing was done at three different carbon steels and the ...
Numerical Simulation of Fatigue Crack Growth in Titanium Alloy Orthopaedic Plates
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Biomaterials intended for orthopaedic plates manufacturing have much higher mechanical properties relative to the bone itself and still there are many cases where those plates fracture in service, with fatigue as the main ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
Microstructure and Wear Behavior of MMC Coatings Deposited by Plasma Transferred Arc Welding and Thermal Flame Spraying Processes
(Springer India, New Delhi, 2020)
In this study, two erosion protection MMC coatings with WC particles were deposited by the plasma transferred arc (PTA) welding. One of the coatings with tungsten carbide WC in the NiBSi matrix (WC/NiBSi), and the second ...
