Investigation of laser surface processing of steel and nickel based superalloy
(Vinča Institute of Nuclear Sciences, 2009)
Investigation was carried out on steel and nickel based superalloy samples. After thermomechanical treatment and adequate preparation, Nd:YAG laser processing was applied. Laser energy was up to 50 mJ, pulse duration 532 ...
Experimental determination of type of fracture pla specimens in the function of printing conditions
(University of Belgrade, faculty of Mechanical Engineering, 2019)
Fused Filament Fabrication (FFF) represent one of the technologies to process polymer materials in the way of rapid prototyping. Parts produced by this method not so rarely have good mechanical properties in the tangential ...
Gauss-type quadrature rules with respect to the external zeros of the integrand
(MNA 2022, Book of abstracts, 2022)
In the present paper, we propose a Gauss-type quadrature rule into which the external zeros of the integrand (the zeros of the integrand outside the integration interval) are incorporated. This new formula with $n$ nodes, ...
Incorporating the external zeros of the integrand into certain quadrature rules
(FAATNA20>22, Book of abstracts, 2022)
Quadrature formulas are often constructed to be exact on the space of functions that are easily integrated and that are in some sense similar to the integrand. This motivates us to examine how the known properties of the ...
Effects of Multiple Defects on Welded Joint Behaviour Under the Uniaxial Tensile Loadring: Numerical and Experimental Approach
(CIBv 2022 International Scientific Conference on Civil Engineering and Building Services, 2022)
The application of reanalysis method (modification of dynamic characteristics) to solve practical problems of structural strength
(Mini-Symposium “Fracture Mechanics and Numerical Methods” Mathematical Institute of SASA and Project OI 174001, 2016)
PM emissions from newly-built wood chip combustion plants: Case study for Serbia
(Belgrade : Vinča Institute of Nuclear Sciences, 2021)
There is evident increase in air pollution in recent years. The dominant sources of air pollution in urban and rural areas, during the heating season, are small individual appliances. In recent years, new combustion plants ...
Model testing of complex structures from the aspects of dynamics
(The Symposium “Nonlinear dynamics - Scientific work of Prof. Dr Katica (Stevanovic) Hedrih”, 2019)
The possibilities of real constructions testing are often limited, especially in case of large
constructions. One of the solutions is to create a sub-scaled model in order to anticipate the
behavior of the real construction, ...
Effect of capacity and fuel type on dust emission from refinery furnace for atmospheric distillation
(Belgrade : Vinča Institute of Nuclear Sciences, 2019)
In order to investigate effect of fuel type and refinery furnace for atmospheric distillation capacity on dust emission field tests are performed. Tests include two different fuels (only refinery gas and mixture of 30% ...
Designing of manufacturing process of reformer integrated in system with HTPEM fuel cell stack
(International Conference of Experimental and Numerical Investigations and New Technologies, CNN TECH 2017 - The Book of Abstracts, pp.51, Zlatibor, Serbia, 02-05 July, 2017, 2017)
In this paper is shown designing of manufacturing process of reformer in polymeric electrolyte membrane (PEM) fuel cell. The process is based on reformer modelling, analyzing of reforming initial geometry and change of ...
