The initial analysis of the river Ibar temperature downstream of the lake Gazivode
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
As a result of a very limited number of geometric and other input data, the temperature modeling of the river Ibar downstream of the lake Gazivode was started by analyzing one river reach between Pridvorica, secondary dam ...
Remaining life assessment of a high pressure turbine casing in creep and low cycle service regime
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thick walled components such as high pressure (HP) steam turbine casings operating under high parameter conditions are subjected to a complex stress state. As a result of that stress state, some parts of HP turbine casing ...
Influence of furnace tube shape on thermal strain of fire-tube boilers
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this paper is to use numerical analysis and fine element method-FEM to investigate the influence of furnace tube shape on the thermal strain of fire-tube boilers. Thermal stresses in corrugated furnace tubes of ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Modeling of the buckstay system of membrane walls in watertube boiler construction
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is ...
Uncertainty evaluation of the conducted emission measurements
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
For the evaluation of measurement uncertainty in measuring the conduction emission, in this paper we propose a new model which uses mixed distribution. Evaluation of probability density function for the measurand has been ...
Isogeometric bending analysis of composite plates based on a higher-order shear deformation theory
(Korean Soc Mechanical Engineers, Seoul, 2014)
This research paper presents an isogeometric plate finite element formulation for analysis of thick composite plates. Isogeometric finite element method which is based on non-uniform rational B-splines (NURBS) basis ...
The failure analysis of the star-separator of an aircraft cannon
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper analyzes the causes of fracture of the double pipe aerial cannon stellate starseparator, which occurred during the fighting plane mission. The linear finite element method (FEM) is used to determine the stresses ...
Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Springer Heidelberg, Heidelberg, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
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 ...
