Hysteretic behavior modeling of elastoplastic materials / Modeliranje histerezisnog ponašanja elastoplastičnih materijala
(Srpsko društvo za mehaniku, Beograd, 2008)
In the present paper the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular ...
Nelinearna analiza stabilnosti okvirnih nosača
(Univerzitet u Nišu - Građevinsko-arhitektonski fakultet, Niš, 2009)
The research related to work on my doctoral thesis is presented in this paper. The basic subject of proposed PhD research is related to the numerical simulation of elastic and non-elastic stability analysis of frame ...
Discrete Kirchof theory of thin shells based on triangular finite element, II / Diskretna Kirchofljeva teorija tankih elastičnih ljuski izvedena iz trougaonog konačnog elementa, II
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2002)
Assuming convected coordinate frame, a three node triangular shell element which uses a discrete Kirchof bending formulation is presented. The tangential components and transverse displacement are approximated by complete ...
Analytical solution for multilayer plates using general layerwise plate theory / Analitičko rešenje višeslojnih ploča zasnovano na opštoj laminatnoj teoriji ploča
(Univerzitet u Nišu, Niš, 2005)
This paper deals with closed-form solution for static analysis of simply supported composite plate, based on generalized laminate plate theory (GLPT). The mathematical model assumes piece-wise linear variation of in-plane ...
Pravilne konkavne kupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
The term cupola stands for a polyhedron consisting of two regular polygons: n-gon and 2n-gon in parallel planes, connected by an alternating series of squares and equilateral triangles, ie. Johnsonsolids J3, J4 and J5. ...
Zlatni presek i pravilne konkavne bikupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
Zlatni presek (racio) predstavlja odnos između strane pravilnog pentagona i njegove dijagonale, a takođe se dovodi u vezu sa susednim članovima Fibonacijevog niza. Istraživaem i upoređivanjem metričkih parametara konkavnih ...
Multilayer Plate Finite Element / Konačni element višeslojne laminatne ploče
(Faculty of Civil Engineering of the University of Belgrade─Chair for Technical Mechanics and Theory of structuresGrađevinski fakultet Univerziteta u Beogradu─Katedra za Tehničku mehaniku i teoriju konstrukcija, 2009)
Under the manufacturing and service conditions, laminated composites are exposed to various damage modes, on the local or ply level. As 2D plate models are capable only to determine global behaviour of laminated composites, ...
Prostorna interpretacija Hugelschaffer-ove konstrukcije jajaste krive
(Niš: Faculty of Architecture and Civil Engineering in Niš; Serbian Society for Geometry and Graphics (SUGIG), 2008)
Konstrukcija jajaste kubne krive Hügelschäffer-ovom metodom, zasniva se na konstrukciji elipse metodom koncentričnih krugova različitih radijusa, a i b, koji odgovaraju parametrima elipse. Načinjen je pokušaj da se prostornom ...
A finite element based on a generalized laminated plate theory / Konačni element zasnovan na Opštoj laminatnoj teoriji ploča
(Fakultet tehnickih nauka-Institut za građevinarstvo, Novi Sad, Građevinski Fakultet Univerziteta u Beogradu, Ministarstvo nauke i zaštite životne sredine republike Srbije, 2005)
In this paper a plate bending element based on Generalized layerwise plate theory (GLPT) is formulated. The finite element accounts for transverse shear deformationa and layer-wise description of in-plane displacement ...
Konstruktivna obrada hiperboličke spirale kao centralne projekcije cilindrične zavojnice
(Novi Sad: Fakultet tehničkih nauka, 2006)
Centralna projekcija cilindrične zavojnice jeste ravna transcedentna kriva, u najopštijem slučaju. U određenim slučajevima, ta kriva će biti upravo spiralna kriva. U specijalnom slučaju, kada se osovina cilindra poklapa ...
