A theoretical model for vibro-impact dynamics of spur gears with tooth flanks wear
(NODYS Publications, Rome, Italy, 2019)
The main performances of involute gears operations lead to the appearance of nonlinear dynamic behaviour and impact. In this paper the influence of mild wear of the tooth flanks of gears without surface hardening on the ...
Gas cylinder rupture induced by local corrosion damage
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
Commercial gas cylinders are common type of pressure vessels in many health care and technical facilities. Unexpected
failures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
Simulation of the kinematic hardening of AISI 316 steel by nonlinear finite element analysis
(Serbian Society of Mechanics and Faculty of Technical Sciences Novi Sad, Serbia, 2015)
The coupled non-linear transient calculation is performed and explained in order to simulate the kinematic hardening behavior of AISI 316 steel and the Finite Element Method (FEM) is used for presented simulation. The ...
Comprehensive approach to weld repair on elements of power transmission – case study for hydro turbine shaft
(Proceedings of the The 4th IIW South – East European Welding Congress, October, 10-13, 2018, Belgrade, 2018)
Turbine and generator rotors and shafts undergo high
stresses during regular working life and, from a safety
and operational aspect, are the most significant
components of a power generation system. Depending
on the ...
Stress concentration factors in re-evaluation of design solution
(Serbian Society of Mechanics and Faculty of Technical Sciences Novi Sad, 2015)
The failures of various parts of mechanical systems in powe industry are the lessons that should be learned thoroughly. Every behaviour of structure close to design encelope must be ecxamined carefully in order to minimize ...
Modal analysis of the hydro turbine shaft with cracks
(Abstracts of 14th International conference Dynamical Systems - Theory and Applications, 2017)
The design process for the elements which are the parts of the structures and equipment in power industry includes both of stress and strain state calculations, as well as an analysis of natural mode shapes and frequencies. ...
Inkrementalna, totalna i hibridna formulacija u adaptivnoj pushover analizi zgrada
(Zbornik-PHIDAC 2010, II Simpozijum studenata doktorskih studija iz oblasti građevinarstva, arhitekture i zaštite životne sredine, Fakultet tehničkih nauka, Novi Sad, Srbija, 2010)
U ovom radu se razmatraju numerički aspekti određivanja i korekcije lateralnih sila
primenjujući inkrementalnu, totalnu i hibridnu formulaciju. Generalni postupak za sprovođenje
nelinearne analize zgrada je inkremental ...
O aspektima modeliranja temeljnog nosača i tla za FEM analizu
(GEOREKS 2010, IV regionalni kongres studenata geotehnoloških fakulteta, Vrnjačka Banja, Srbija,, 2010)
U ovom radu su prikazani aspekti modeliranja izdvojenog temeljnog nosača i tla za uticaj statičkog opterećenja. Temeljni nosač je razmatran primenom linijskih, površinskih i prostornih konačnih elemenata, dok je tlo ...
Poboljšanje adaptivne FBA pushover analize primenom neelastičnog spektra odgovora u spektralnoj amplifikaciji seizmičkih sila
(Zbornik-Zemljotresno inženjerstvo i inženjerska seizmologija, II naučno-stručno savetovanje, Divčibare, Srbija, 2010)
Istraživanje prikazano u ovom radu uvodi dodatnu korekciju adaptivne FBA pushover analize koja se zasniva na proračunu prema silama. U odnosu na klasičnu adaptivnu FBA pushover analizu sa elastičnim spektrom odgovora za ...
Analiza ciljnog pomeranja 3D modela objekta i tla za uslove seizmičkog dejstva
(Istraživanja, projekti i realizacija u graditeljstvu, Međunarodni naučno-stručni skup povodom stogodišnjice rođenja akademika Prof. Branka Žeželja, Institut IMS, Beograd, Srbija, 2010)
Istraživanje prikazano u ovom radu tretira problematiku interakcije objekat-temeljna konstrukcija-3D model tla primenom nelinearne statičke seizmičke analize. Pushover krive su razvijene uzimajući u obzir da lateralno ...
