Unapređenje tehnologije aluminotermijskog zavarivanja železničkih šina različitog poprečnog preseka / Improvement of at-welding technology of railway rails with different cross sections
(Savez inženjera i tehničara Srbije, Beograd, 2021)
U radu je prikazana nova tehnologija aluminotermijskog zavarivanja (AT) prelaznih šina 49E1 na 60E1(EN 13674-1:2005.), oslonjena na potpuno nove materijale. Ona se odnosi na pešćane kalupe kod kojih su oblik i dimenzije ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
The characterization and pollution status of the surface sediment in the Boka Kotorska Bay, Montenegro
(Springer Heidelberg, Heidelberg, 2021)
Surface sediments collected from twelve stations in the Boka Kotorska Bay were analyzed for the level and distribution of twenty-six elements and ten oxides, grain sizes, organic matter, and carbonate content. Potentially ...
Determination of the Coffin-Manson equation under low-cycle fatigue conditions
(Institut za ispitivanje materijala, Beograd, 2021)
The cycle loading of a material results in the modification of its properties and so in this paper is presented the behaviour of the fatigue life using low-cycle fatigue parameters. By applying the Coffin-Manson equation ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Univ Zagreb Fac Mechanical Engineering & Naval Architecture, Zagreb, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
Application of fly ash to reduce soil dispersivity in embankments
(Publ House Bulgarian Acad Sci, Sofia, 2021)
Due to rapid development of modern highways and railroad in Serbia, the need for embankment materials has increased. Deposits of natural materials used for this purpose often contain dispersive soils. On the other hand, ...
Geochemical characterization of sediments from the archaeological site Vinca - Belo Brdo, Serbia
(Elsevier, Amsterdam, 2021)
In this study, a multidisciplinary approach was used for a detailed characterization of sediments from the archaeological site Vina. - Belo Brdo, Serbia, one of the most important Neolithic settlements in Europe. This ...
Comparative analysis of current standards for testing thermal protection of facade carpentry
(Regional Association for Security and Crisis Management-RASEC S4 GLOSEC Global Security, 2021)
The low level of energy efficiency in buildings results in increased energy
consumption for heating and cooling and high carbon dioxide emissions. Insufficient
thermal protection of the exterior of a building contributes ...
