Experimental and numerical thermo - mechanical analysis of friction stir welding of high - strength alluminium alloy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents experimental and numerical analysis of the change of temperature and force in the vertical direction during the friction stir welding of high-strength aluminium alloy 2024 T3. This procedure confirmed ...
Comprehensive approach to the influence of frequently used secondary raw materials on clay bricks quality using mathematical modeling (a systematic review)
(Elsevier Sci Ltd, Oxford, 2018)
The main idea of this research was to evaluate rice and sunflower hulls, sawdust and their ashes, as additives in clay brick production using mathematical analysis. All available papers, containing the parameters of interest, ...
Failure analysis of the mobile elevating work platform
(Elsevier Ltd, 2015)
This paper presents an investigation of the accident which occurred during startup of the extending structure from the transport position. In order to clarify the causes of crack occurrence along almost the entire surface ...
Energy conversion in phosphate ore grain mixture activated via ultra-centrifugal mill
(Elsevier, Amsterdam, 2015)
The aim of this investigation was to establish the optimal processing parameters of the comminuted phosphate grain mixture mechanical treatment by monitoring and evaluating the activated product characteristics. An ...
Behaviour of nionikral-70 in low-cycle fatigue
(Institut za ispitivanje materijala, Beograd, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
Experimental study on the stresses at the i-beam end-plate moment connection
(Institut za ispitivanje materijala, Beograd, 2019)
The paper deals with experimental study of the stresses at the bolted end-plate moment connection. The design parameters are adopted to include prying effects in joint. A stress level is obtained in the elements where the ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (HSLA) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
Predviđanje optimalnih parametara interventnog reparaturnog zavarivanja čelika 13CrMo4-5 analitičkim metodama / Optimal parameters estimation by the analytical methods for the emergency repair welding of the 13CrMo4-5 steel
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2010)
Već dugi niz godina se čelik 13CrMo4-5 (~Č7400) primenjuje za izradu delova termoenergetskih postrojenja kao što su elementi kotlova i cevi. Ovaj čelik pripada grupi uslovno zavarljivih čelika, koji mogu uspešno da se ...
Activated carbons obtained by pyrolyzing of resorcinol formaldehyde gels
(University of East Sarajevo, Faculty of Technology, 2010)
Activated carbon is used in different industrial domains due to highly developed specific surface area and its specific chemistry. Properties of activated carbons obtained by pyrolyzing formaldehyde gels are presented in ...
Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis
(Savez hemijskih inženjera, Beograd, 2010)
Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. ...
