Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model / Uticaj ograničenog deformisanja na nastanak žilavog loma korišćenjem kompletnog Gursonovog modela - numerička simulacija
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2010)
Ductile fracture initiation in high-strength low alloyed welded steel joints is predicted using micromechanical complete Gurson model (CGM). The crack tip constraint and variation of stress triaxiality in ligament are ...
Characterization of plasma spray bioinert coating Al2O328wt.%MgO / Karakterizacija plazma sprej bioinertne prevlake Al2O328tež.%MgO
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
This paper presents the results of testing mechanical and structural characteristics of plasma spray coating Al2O328wt.%MgO. Metal oxide MgO in a complex oxide Al2O328wt.%MgO modifies the properties of Al2O3 ceramics by ...
Change of temperature and vertical force during friction stir welding / Promena temperature i vertikalne sile tokom procesa zavarivanja trenjem mešanjem
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2013)
The aim of this paper is to analyze changes of vertical force and temperature during friction stir welding process of high strength aluminum alloys (2024 T3). FSW process is a complex nonlinear process accompanied by large ...
Mechanical properties and microstructure of molybdenum coating layers deposited vacuum plasma spray process / Mehanička svojstva i mikrostruktura slojeva prevlake molibdena deponovane vakuum plazma sprej procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Molybdenum coatings due to their excellent wear resistant properties and sliding characteristics under dry friction conditions are often used in applications to resist friction and dry sliding. Since molybdenum metal is ...
Numerical simulation of the plunge stage in friction stir welding / Numerička simulacija faze uranjanja kod zavarivanja trenjem mešanjem
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
This paper investigates the plunge stage using numerical modeling. A three-dimensional finite element model (FEM) of the plunge stage is developed using the commercial code ABAQUS to study the thermo-mechanical processes ...
Investigations of the possibilities of stillage utilization from the bioethanol production on corn / Ispitivanje mogućnosti korišćenja džibre iz proizvodnje bioetanola iz kukuruza
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2010)
Bioethanol produced by fermentation of biomass, such as sugar, starch, or lignocellulosic materials, is one of the most important renewable energy resources. An average thin stillage amount produced in the bioethanol process ...
Estimation of GHG emission in Serbia for period 1995-2013 using recurent neural networks / Emisije gasova staklene bašte u Srbiji za period 1995-2013. godina primenom rekurentnih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The aim of this work was to create an ANN model for the prediction of GHG emissions in the Republic of Serbia in the period 1995-2013. Because of the lack of GHG emission data and inputs for Serbia, the ANN model was ...
Quality, sources and balancing of iron and steel scrap / Kvalitet, izvori i bilansiranje otpadaka gvožđa i čelika
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
Leaching of chalcopyrite concentrate by hydrogen peroxide in sulphuric acid solution / Luženje halkopiritnog koncentrata rastvorom sumporne kiseline i vodonik-peroksida
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Due to complex mineralogy and/or low content of base metals, some ores and mineral concentrates are not suitable for pyrometallurgical treatment. Therefore, those ores and concentrates have to be treated by application of ...
