Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
Mechanical properties of composites based on unsaturated polyester resins obtained by chemical recycling of poly(ethylene terephthalate) / Mehanička svojstva kompozita na bazi nezasićenih poliestarskih smola dobijenih hemijskom reciklažom poli(etilen-tereftalata)
(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
Analysis of the tool plunge in friction stir welding comparison of aluminum alloys 2024 t3 and 2024 t351
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Temperature, plastic strain and heat generation during the plunge stage of the friction stir welding of high-strength aluminum alloys 2024 T3 and 2024 T351 are considered in this work. The plunging of the tool into the ...
Ultrasonographic assessment of the maxillary artery and middle meningeal artery in the infratemporal fossa
(John Wiley and Sons Inc, 2019)
Purpose: To investigate with Doppler ultrasonography the maxillary and middle meningeal arteries in the infratemporal fossa, and describe their hemodynamic characteristics. Methods: We included 24 female and 11 male ...
Improvement of cavitation resistance of composite films using functionalized alumina particles
(Savez hemijskih inženjera, Beograd, 2018)
Composite films having the UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina (Al2O3 Fe) based particles were prepared and subjected ...
Experimental Investigation of Microstructure and Phase Transitions in Ag-Cu-Zn Brazing Alloys
(Springer, 2018)
Microstructure and phase transitions of selected brazing alloys from the Ag-Cu-Zn ternary system were investigated. Four ternary alloys with silver content in the compositional range from 25 to 60 wt.% were studied using ...
A Spontaneous Cervical Epidural Hematoma Mimicking a Stroke: A Challenging Case
(Elsevier USA, 2019)
Background: A spontaneous cervical epidural hematoma (SCEH) is a rare occurrence, with < 500 cases reported to date. Clinically, it usually presents with quadriparesis, but in extremely rare cases it can present with ...
