Initial development of the hybrid semielliptical-dolphin airfoil
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Iosif Taposu has formulated a mathematical model and generated a family of air-foils whose geometry resembles the dolphin shape. These airfoils are characterized by a sharp leading edge and experiments have proven that ...
Corrosion effects on structural integrity and life of oil rig drill pipes
(Savez hemijskih inženjera, Beograd, 2022)
Corrosion effects on structural integrity and life of oil rig welded pipes are analysed by experimental, analytical, and numerical methods. Experiments were performed using standard tensile specimens and CT specimens for ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical ...
Optical stereometric analysis of an experimental partially-edentulous mandible
(Sage Publications Ltd, London, 2022)
Stereooptics method have been successfully used in biomechanical studies of dental models. The aim of this study was to investigate, on the basis of functional deformities, the distribution of occlusal loads on the casts ...
Numerical simulation of titanium alloy hip replacement implants behaviour under static and dynamic loads
(HEMIJSKA INDUSTRIJA (Chemical Industry), 2023)
This paper presents development of numerical models for simulation of the behaviour of titanium alloy hip implants under static and dynamic loads, which is a part of extensive research involving the structural integrity ...
Research of expendable turbojet tubular combustion chamber
(Sage Publications Ltd, London, 2022)
This paper presents research related to the tubular combustion chamber of an expendable turbojet. Although annular combustors are dominant at present, tubular combustors are still attractive because they are simpler to ...
Microstructure and fracture mode of unalloyed dual-phase austempered ductile iron
(Savez hemijskih inženjera, Beograd, 2022)
Dual-phase ADI material microstructure consists of different amounts and morphologies of ausferrite and free ferrite, obtained by subjecting ductile iron to specific heat treatment. Its strength is lower compared to ...
Thermo-mechanical analysis of linear welding stage in friction stir welding influence of welding parameters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The influence of friction stir welding parameters on thermo-mechanical behav-ior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Analysis and design of the gas generator multifunctional bulkhead considering the thermal and structural loads
(Sage Publications Ltd, London, 2022)
The operation of gas generators brings relatively high thermo-mechanical loads on the gas generator structure. The objective of this article is to determine the operating conditions, in terms of mechanical loads at extremely ...
