MKE model zupčanika sa kosim zupcima za analizu naponskog stanja i nelinearnu analizu kontakta / Finite element model for stress analysis and nonlinear contact analysis of helical gears
(Vojnotehnički institut, Beograd, 2009)
Određivanje naponskog i deformacionog stanja na bokovima i u podnožju zubaca jedan je od osnovnih zadataka u toku proračuna opterećenja i provere nosivosti zupčanika. U ovom radu opisan je postupak razvijanja modela konačnih ...
Microstructure and fracture of alloyed austempered ductile iron
(Elsevier Science Inc, New York, 2006)
An investigation has been conducted on two austempered ductile irons alloyed with Cu and Cu+Ni, austenitized at 900 degrees C and austempered at 350 degrees C. The microstructure and fracture mode developed through these ...
