The pencil of the 4th and 3rd order surfaces obtained as a harmonic equivalent of the pencil of quadrics through a 4th order space curve of the 1st category / Pramen površi 4. i 3. reda dobijen kao harmonijski ekvivalent pramena kvadrika kroz prostornu krivu 4. reda 1. vrste
(Univerzitet u Nišu, Niš, 2012)
This paper shows the process of inverting the 4th ordered space curve of the first category with a self-intersecting point (with two planes of symmetry) and determining its harmonic equivalent. There are harmonic equivalents ...
Polyhedral forms obtained by combinig lateral sheet of CP II-10 and truncated dodecahedron / Poliedarske forme nastale spajanjem omotača CP II-10 i zarubljenog dodekaedra
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
The paper analyzes the possibility of obtaining polyhedral shapes formed by combining polyhedral surfaces based on the segment surface of elongated concave pyramids of the second sort (CeP II-10, type A and type B). In ...

Environmental assessment of copper slag aggregate concrete
(DIMK. DGKS i Građevinski fakultet Univerziteta u Beogradu, 2022)
Due to the extremely large global production and utilization of concrete, the concrete
industry is considered a large consumer of energy and natural resources and one
of the main sources of greenhouse emissions and waste ...
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 ...
Local behaviour of the connector with mechanical coupler and rebar anchor under tension load
(Society for Materials and Structures Testing of Serbia; Faculty of Civil Engineering, University of Belgrade, Serbia; Association of Structural Engineers of Serbia, 2023)
In the past few decades, demountable connectors have often been used for
connections in composite and mixed steel-concrete structures to reduce
construction time and costs. Furthermore, the application of demountable
connectors ...
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. ...
