Some results of RIMAP based RBIM implementation on the example of 21 000 components in refinery Pancevo are presented in this paper. It is proved to be a powerful tool for maintenance planning, for increasing industrial ...
Korelacija digitalne slike u analizi eksperimentalne mehanike / Digital image correlation in experimental mechanical analysis
(Institut za ispitivanje materijala, Beograd, 2012)
Korelacija digitalne slike (DIC) je moćna beskontaktna tehnika za merenje polja pomeranja/deformacija na površinama. Neke metode, zasnivane na 2D analizi, se koriste za određivanje mehaničkih osobina epruveta jednostavnih ...
Lom konstrukcije strele odlagača rotornog bagera C 700 S usled dinamičkih uticaja / The structure failure of the discharge boom of bucket wheel excavator C 700 S due to dynamic effects
(Institut za ispitivanje materijala, Beograd, 2012)
Tokom operacije, kod rotornog bagera (BWE) se razvilo nepovoljno dinamičko ponašanje, plastična deformacija i lom konstrukcije. Posle sprovedene eksperimentalne/numeričke analize, potvrđeno je rezonantno dinamičko ponašanje ...
Crack resistance of aluminium alloy friction stir welded joint
(Institut za ispitivanje materijala, Beograd, 2015)
Charpy testing is conducted on a high-speed data acquisition instrument, using instrumented pendulum to separate energies for crack initiation and propagation. The J-R curves are used to determine JIc, as the measure of ...
