Uticaj orijentacije vlakana na udarnu žilavost i osobine loma kompozita ugljenična vlakna - epoksi smola / The effect of fiber orientation on impact toughness and fracture properties of carbon fiber-epoxy composite
(Institut za ispitivanje materijala, Beograd, 2002)
Uticaj orijentacije ugljeničnih vlakana u kompozitu sa epoksi matricom na udarnu žilavost i na žilavost loma je eksperimentalno analiziran ispitivanjem Šarpi epruveta sa V zarezom i zarezanih epruveta modifikovanog CT ...
Čelici za armiranje betona / Steels for concrete reinforcement
(Institut za ispitivanje materijala, Beograd, 2005)
Ispitivanje čelika u građevinarstvu danas uključuje obimnu aktivnost koja nije na pravi način prikazana u domaćoj stručnoj literaturi. Ispitivanje je od velikog značaja u slučaju čelika za armiranje betona, jer može doći ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
Helicopter Rotor Blade Shape Optimization Using NURBS for Airfoil Shape Parameterization
(AIP Conference Proceedings, 2009)
An introductory study of helicopter main rotor blade aerodynamic shape optimization problem is presented. Optimization process is carried out in compressible, viscous, quasi-steady fluid flow field of hovering rotor described ...
An analysis of the influence of weldment heterogeneity in ferrite-austenite welded structure
(Welding in the World, 2009)
An analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested ...
