Numerical simulation of welded joint with multiple various defects
(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents continuation of extensive work on determining the behaviour of welded joints in the presence of multiple various types of defects, a problem that is not sufficiently covered by existing standards, such ...
Repair welding procedure and techno-economic analysis of burner pipe
(Institut za ispitivanje materijala, Beograd, 2021)
The selection of the electrode for repair welding is one of the activities needed before repairing machine parts. In this case, damages that have occurred in a burner pipe welded joint during manufacture or previous repair ...
Finite element analysis of spherical storage tank stress state
(Institut za ispitivanje materijala, Beograd, 2021)
In this paper, a spherical storage tank for the storage of liquefied petroleum gas is analysed. A design calculation of structural elements is performed according to valid standards and technical regulations. Seismic loads ...
Fenomen misije u srpskim kompanijama / The phenomenon of mission in Serbian companies
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2019)
Izjava o misiji je personifikacija identiteta organizacije i služi kao osnova za sve zaposlene da se identifikuju sa organizacijom. Dobro definisana misija obezbeđuje stabilnost organizacije jer daje jasan pravac kretanja ...
Komparativna nelinearna analiza interakcije šip-tlo AB 2D rama / Comparative nonlinear analysis of a RC 2D frame soil-pile interaction
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
U radu je sprovedena komparativna nelinearna statička (NSA) i nelinearna dinamička analiza (NDA) seizmičkog ponašanja rama kao dela skeletne konstrukcije AB zgrade fundirane na šipovima. Da bi se dobila realnija slika ...
