Statistical processing the results of interlaboratory testing the grain-size distribution of sand and gravel from the western part of the Kostolac basin / Statistička obrada rezultata međulaboratorijskog ispitivanja granulometrijskog sastava peska i šljunka iz zapadnog dela kostolačkog basena
(Institut za rudarstvo i metalurgiju, Bor i Komitet za podzemnu eksploataciju mineralnih sirovina, Resavica, 2012)
This paper presents the results of interlaboratory testing the grain-size distribution of sand and gravel on representative samples from the site of the western part of the Kostolac Basin. The results were statistically ...
Thermal-stress behaviour of RCC gravity dams / Termičko naponsko stanje gravitacionih brana od valjanog betona
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2015)
Roller Compacted Concrete (RCC) is a special concrete mixture with low cement content, frequently used for concrete gravity dams. This paper deals with the 3D finite element model for unsteady phased thermal-stress analysis ...
Strengthening of timber beams using FRP bars / Ojačanje drvenih greda primenom FRP šipki
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
The growing need for the reinforcement of timber beams (required due to deterioration or damage to the material or change of use) has led to the development of new methods of reinforcement with modern materials. In the ...
Frequency- and time-domain methods related to flutter instability problem / Metode analize flatera u frekventnom i vremenskom domenu
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Bridge flutter phenomenon presents an important criterion of instability, which should be considered in the bridge design phase. This paper presents different bridge flutter methods which can be used to solve the flutter ...
Simple analysis of daylight saving time effects in Belgrade climate and latitude
(Institut za arhitekturu i urbanizam Srbije, Beograd, 2018)
Contemporary controversy about daylight saving time (DST) is mainly derived from different standpoints in studies investigating the positive and negative effects of the clock shift during summer period. From the standpoint ...
Thermo-elastic stability of angle-ply laminates - application of layerwise finite elements
(Institut za ispitivanje materijala, Beograd, 2016)
In this paper thermal buckling analysis of angle-ply laminates is analysed using Generalized Layerwise Plate Theory (GLPT) of Reddy, /1/. The finite element solution is derived from the weak form of the problem. The nine-node ...
Paper strips driven design: Application on doubly curved surfaces / Dizajniranje papirnim trakama - primena na dvostruko zakrivljenim površima
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
In this paper, we address the challenge of overcoming the problem of developing doubly curved surfaces in product design. Product design uses two kinds of surfaces, developable surfaces and non-developable surfaces, which ...
Fiber finite element in nonlinear analysis of square CFT columns / Fiber konačni element u nelinearnoj analizi kvadratnih spregnutih CFT stubova
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
The paper presents nonlinear analysis of square CFT columns using distributed plasticity fiber elements. Behaviour of CFT columns is nonlinear and it is necessary to include different nonlinear effects into the numerical ...
Redistribution effects in linear elastic analyses of continuous composite steel-concrete beams according to Eurocode 4 / Redistribucija uticaja u linearno elastičnoj analizi spregnutih kontinualnih nosača od čelika i betona prema Evrokodu 4
(Univerzitet u Nišu, Niš, 2011)
Different analytical methods, with different levels of approximations and accuracy, are available for analysis of continuous composite steel-concrete beams. The Eurocode 4 recommends few simple methods for calculation of ...
Nonlinear stability analysis of the frame structures / Nelinearna analiza stabilnosti okvirnih nosača
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
In this paper the phenomenon of instability of frames in elasto-plastic domain was investigated. Numerical analysis was performed by the finite element method. Stiffness matrices were derived using the trigonometric shape ...
