Finite Element Analysis of Propagating Delamination in Laminated Composite Plates
(Univerzitet u Beogradu, Građevinski fakultetUniverzitet Crne Gore, Građevinski fakultet Podgorica, 2016)
In the paper, an algorithm to track a moving delamination front of arbitrary shape is proposed, which allows considering of arbitrary meshes composed of 4- and 9-node quadrilateral finite elements. The proposed model is ...
Layerwise Finite Element for Thermal Stability Analysis of Laminated Composite Plates / Slojeviti konačni element za analizu termičke stabilnosti laminatnih kompozitnim ploča
(University of Montenegro / Faculty of Civil EngineeringUniverzitet Crne Gore / Građevinski fakultet, 2016)
In this paper thermal stability of laminated composite plates is analyzed using layerwise finite element. The weak form of the plate mathematical model is derived using layerwise displacement field of Reddy [1], nonlinear ...
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 ...

Influence of Soil-Structure-Interaction on Nonlinear Time History Seismic Response of RC Frames
(Savez građevinskih inženjera Srbije, Beograd, 2016)
Modern regulations require from engineers to take into account a non-linear behavior and the appearance of plastic hinges in the selected structural elements during the earthquake. Also, regulations more insist on considering ...
Elastoplastična analiza rešetkastih nosača sa oštećenjem pri cikličnom opterećenju

U ovoj doktorskoj disertaciji je razmatrano ponašanje rešetkastih konstrukcija u plastičnojoblasti sa ciljem da se optimizuje numerička analiza ovog problema i da se definiše osnovaza proširivanje odgovarajućeg modela na ...
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 ...
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 ...
Finite element modeling of free vibration problem of delaminated composite plates using Abaqus CAE
(Univerzitet Crne Gore, Građevinski fakultet, Podgorica, 2016)
The aim of this paper is to discuss different finite element models of laminated composite plates with delaminations using the commercial software Abaqus CAE. Three-dimensional (solid), as well as two-dimensional (shell) ...
Testing heuristic optimisation methods for vibration-based detection of damage
(Union of Croatian Civil Engineers and Technicians, 2016)
Considerable efforts have been made in recent years for the development of non-destructive techniques for detection of structural damage based on changes of dynamic parameters of structures. The tests are made on a model ...
