Reduction of production cycle time by optimising production and non-production components of time in the metalworking industry: a case study
(Southern African Inst Industrial Engineering, Pretoria, 2016)
The production cycle (PC) time, as a very important economic indicator of freezing current assets, involves the time needed to manufacture a unit or a series of units, from putting them into production until they are put ...
Two-dimensional numerical analysis of active flow control by steady blowing along foil suction side by different urans turbulence models
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The effects of active separation control by steady blowing jets were investigated numerically on three different examples: subsonic flow past Aerospatiale A airfoil at 13 degrees angle-of-attack, transonic flow past NACA ...
The influence of temperature on mechanical properties of the base material (BM) and welded joint (WJ) made of steel S690QL
(Faculty of Metallurgy, 2016)
This paper presents the analysis of the influence of temperature on mechanic properties of the base material and welded joints made of high strength steel. The joints were welded on S690QL high strength steel plates using ...
Effect of aging on mechanical properties of Al-8Si-8Fe-1.4v/SiCp composites
(Faculty of Metallurgy, 2016)
In this study, Al-8Fe-8Si-1.4V/SiCp composites fabricated by squeeze casting process were age-hardened to Study the influence of heat treatment on mechanical properties, such as hardness, bending strength and modulus of ...
Selection of the optimal hard facing (HF) technology of damaged forging dies based on cooling time t8/5
(Faculty of Metallurgy, 2016)
In exploitation, the forging dies are exposed to heating up to very high temperatures, variable loads: compressive, impact and shear. In this paper, the reparatory hard facing of the damaged forging dies is considered. The ...
Energy performance of single family houses in Serbia analzsis of calculation procedures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Energy certification of buildings in Serbia was introduced in 2011 and energy label depends on energy need for heating per unit floor area of heated space, calculated by the fully prescribed monthly quasi-steady-state ...
Numerical Evaluation of the Elastic Properties of Carbon Fiber Reinforced Composite Material at Elevated and Lowered Temperatures
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
The effect of elevated and lowered temperatures on the elastic properties of carbon fiber-epoxy composite material was studied using multi-phase unit cell (MPUC) numerical model. Evaluation of the elastic properties of ...
Numerical analysis of a hypersonic turbulent and laminar flow using a commercial cfd solver
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
Computational fluid dynamics computations for two hypersonic flow cases using the commercial ANSYS FLUENT 16.2 CFD software were done. In this paper, an internal and external hypersonic flow cases were considered and ...
Rapid evaluation of maintenance process using statistical process control and simulation
(Daaam International Vienna, Vienna, 2018)
There are successful and less successful maintenance systems (MS). As a dynamic category, the success of the maintenance function must be taken into consideration both for the present day and the future. This is the reason ...
