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 ...
Supercritical flow in circular pipe bends / Burno tečenje u krivini kružne cevi
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
In this paper a complex flow pattern occurring in a closed conduit bend with supercritical flow is analyzed. The research was done by a scale (physical hydraulic) model, and a numerical model developed in Ansys (Fluent) ...
Management of stresses in the rails on railway bridges / Upravljanje naponima u šinama na železničkim mostovima
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
This paper analyses the stresses in continuous welded rails on bridges including the aspect of fatigue of rail steel. Furthermore, it examines the possibility to avoid rail expansion joints, while simultaneously exploiting ...
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 ...
Perception of 3D Virtual Road Markings - Based on Estimation of Vehicle Speed
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Excessive speed and poor drivers' perception are the causes of a large number of traffic accidents. Analysis of the influence of geometry in drivers' behavior has been widely performed by different researchers. One way to ...
Corrosion of cannon 75/27, model 1911. déport, from the collection of the Military Museum in Belgrade / Korozija topa 75/27, model 1911. deport iz kolekcije Vojnog muzeja u Beogradu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
Stepped spillway flow: Comparison of numerical and scale models / Strujanje u stepenastom brzotoku - poređenje rezultata fizičkog i numeričkog modela
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
This paper deals with flow modelling of the stepped spillway for the Bogovina dam. The analysis was conducted using three approaches: scalemodelling, empirical equations and numerical modelling. An acceptable agreement was ...
On the properties of the concave antiprisms of second sort / O osobinama konkavnih antiprizmi druge vrste
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
The paper examines geometrical, static and dynamic properties of the polyhedral structures obtained by folding and creasing the two-rowed segment of equilateral triangular net. Bases of these concave polyhedra are regular, ...
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 ...
