One possible way of geometrical nonlinear tasks solution / Jedan mogući način rešavanja geometrijski nelinearnih zadataka
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2006)
Assuming convected coordinate frame, strain components are expressed as a average value of a infinitesimal deformations of the unperformed and deformed configurations. From the equilibrium momentum balance equation, using ...
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 ...

(Institut za ispitivanje materijala, Beograd, 2005)
In the present paper numerical analysis of damaged masonry structures using finite element method is presented. Retrofitting of those structures using technology DC90 is outlined to. Experimental results of testing 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 ...
Lateral capacity and deformations of vertical piles loaded by horizontal forces / Bočna nosivost i pomeranja vertikalnih šipova opterećenih horizontalnim silama
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
Pile foundations are frequently loaded by horizontal forces. In such cases, it is important to calculate lateral capacity of vertical piles. It is governed by the strength of the surrounding soil i.e. geotechnical capacity ...
Fiber element formulation for inelastic frame analysis / Formulacija fiber elementa prilikom nelinearne analize ramova
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
The paper discusses two formulations for the fiber based distributed plasticity beam/column element. For force based and displacement based formulations, basic details and main differences are emphasized. The differences ...
Potential and benefit of green roof energy renovation of existing residential buildings with a flat roof in Belgrade
(Applied Sciences, MDPI, 2023)
This paper considers the phenomenon of the instability of steel plane frame structures in the elastic-plastic domain. The numerical analysis uses FEM, where the corresponding stiffness matrices are based upon the trigonometric ...
