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 ...
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 ...
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 ...
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 ...
Properties modeling of cement composites made of fly ash / Modelovanje svojstava maltera primenom elektro-filterskog pepela
(Inženjersko društvo za koroziju, Beograd, 2014)
There is a number of advantages when using fly ash in cement composites. Fly ash is known for decades for its' pozzolanic properties, and thus it is mostly used as an mineral admixture in the process of production of cement. ...
Railway bridges on interoperable lines: Aspect of track/bridge interaction / Železnički mostovi na interoperabilnim prugama - aspekt interakcije kolosek/most
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
The Institute for Standardization of Serbia has adopted a large number of en standards in the field of bridges as Serbian standards. Unfortunately, technical regulations based on the implementation of the adopted en standards ...
The Advantages of Using Digital 3D Animation in Geometrical Education
(University of Belgrade, Faculty of Architecture, with The Centre for Ethics, Law and Applied Philosophy, 2017)
New media technologies and interdisciplinary approach is used and represented in this paper. The aspects and research results are shown through the production methodology, multimedia learning tool and the final application ...
Rail traffic volume estimation based on world development indicators
(Univerzitet u Nišu, Niš, 2015)
European transport policy, defined in the White Paper, supports shift from road to rail and waterborne transport. The hypothesis of the paper is that changes in the economic environment influence rail traffic volume. ...
On the radius and the relation between the total graph of a commutative ring and its extensions
(Srpska akademija nauka i umetnosti SANU - Matematički institut, Beograd, 2011)
We discuss the determination of the radius of the total graph of a commutative ring R in the case when this graph is connected. Typical extensions such as polynomial rings, formal power series, idealization of the R-module ...
Correlation-regression analysis of modelled chlorine residual's spatial variability in water supply network / Korelaciono-regresiona analiza modelirane prostorne raspodele reziduala hlora u vodovodnoj mreži
(Inženjersko društvo za koroziju, Beograd, 2014)
Residual chlorine ex. concentration of free chlorine disinfection able to carry disinfection in drinking water is an important parameter of drinking water, primarily talking about its bacteriological safety. On the other ...
