Optimizing the thermal gradient and the pulling speed in a thermoplastic pultrusion process of pet/e glass fibers using finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2018)
A thermoplastic pultrusion process was examined using commercial fiber roving of PET/E glass, to determine the optimum pulling speed and optimal zonal temperatures. Finite element analysis predicted heat transfer through ...
Micromechanical fracture analysis of laminated glass-epoxy composite material tested by bending / Mikromehanička analiza loma laminatnog staklo-epoksi kompozitnog materijala ispitivanog savijanjem
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The object and purpose of this work is the micromechanical analysis of failures caused by mechanical tests of laminate glass-epoxy composite material in bending. The structure of glass-epoxy composite material is a glass ...
Integrity assessment of vital beam components that enable conjoint operation of two bridge cranes
(Society for Structural Integrity and Life, Institute for Material Testing, 2018)
Vital components of the beam that enable conjoint operation of two bridge cranes are braces and threaded spindle. The beam connects two bridge cranes with overall lifting capacity of 500 t (2 x 250 t) and enables their ...
Influence of encastering on thin-walled cantilever beams with u and z profiles on the magnitude of equivalent stress and deformation
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
The purpose of this work is to present analytical and numerical determination of equivalent stress and deformation of open section thin-walled U and Z cantilever beams loaded with torsion. This work can be divided into two ...
Organoclay-polymer nanocomposites / Organoglina-polimerni nanokompoziti
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved ...
Integrity assessment of regulation system pipeline elements in hydroelectric generating set a6 of hydro power plant 'Djerdap 1'
(Society for Structural Integrity and Life, Institute for Material Testing, 2016)
Vertical Kaplan turbines with nominal power of 176 MW manufactured in Russia are installed in 6 hydroelectric generating sets at hydro power plant 'Djerdap 1' (Kladovo, Serbia). Most of the components are made of materials ...
Selection of lactic acid bacteria strain for simultaneous production of α- and β-galactosidases / Izbor mlečnokiselinske bakterije za istovremenu proizvodnju α- i β-galaktozidaza
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Galactosidases are group of enzymes gaining increasing attention in recent times due to the fact they catalyse hydrolysis of galatose-containing oligosaccharide, which reduce digestibility of various food and feed products. ...
Enzymatic lipophilization of vitamin C with linoleic acid: Determination of antioxidant and diffusion properties of L-ascorbyl linoleate / enzimska lipofilizacija vitamina C linolnom kiselinom - određivanje antioksidativnih i difuzionih svojstava L-askorbil-linolata
(Institute for Food Technology, Novi Sad, 2018)
Lipophilic derivatives of vitamin C are additives with antioxidant properties, attractive for application in food, cosmetics and pharmaceutics. They could be synthesized in lipase-catalyzed processes by using various acyl ...
Anodization of Ti-based materials for biomedical applications: A review
(Association of Metallurgical Engineers of Serbia, 2016)
Commercially pure titanium (cpTi) and titanium alloys are the most commonly used metallic biomaterials. Biomedical requirements for the successful usage of metallic implant materials include their high mechanical strength, ...
