Determination of ductile crack initiation by magnetic emission and potential drop techniques using pre-cracked Charpy specimens
(European Structural Integrity Society, 2002)
Magnetic emission (ME) and potential drop (PD) techniques were used for instrumented Charpy impact testing in order to determine critical crack initiation properties of standard pre-cracked three-point bending specimens ...
Formation of fouling layers on a heat exchanger element exposed to warm, humid and solid loaded air streams
(Elsevier Science Inc, New York, 2002)
In consideration of the very high energy consumption of drying processes it is astonishing and disadvantageous that the majority of industrial dryers are offered and operated without energy recovery. The avoidance of fouling ...
Razvoj opreme za proizvodnju peleta od biomase / Development of equipment biomass pellets production
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2004)
S obzirom da biomasa predstavlja obnovljivi vid energije, a da je cena električne energije kao i fosilnih goriva sve veća, došlo je do povećane zainteresovanosti za izradu i nabavku opreme za proizvodnju peleta. Agrarni ...
Using machine learning techniques to enhance expressiveness of computer-based design systems
(Education and research in Computer Aided Architectural Design in Europe, 2000)
In face of the huge expansion of computer-mediated interaction among people, current representation-centered CAAD systems do not offer full information spectrum necessary to express all design intentions. Representational ...
Crystallographic orientations of Ni3Al-based aluminide
(Elsevier Science Inc, New York, 2000)
Inverse pole figures have been plotted to determine preferred crystallographic orientations in a powder-compacted Ni3Al aluminide prealloyed with Fe, Ti and B. The main textural components, although weak, were noticeably ...

Za odabrane grane i celinu sektora industrije Srbije sprovedena je detaljne analiza obima i strukture potrošnje finalne energije u periodu 199Ć-1998. i shodno merilima energetske efikasnosti i proizvodne efektivnosti utvrđen ...
Primena mehanike loma na procenu integriteta konstrukcije / Structural integrity assessment using fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2001)
U radu je dat opšti pristup proceni integriteta konstrukcija primenom mehanike loma. Posebno su analizirani linearno-elastični i elasto-plastični problemi i mogućnosti primene odgovarajućih parametra mehanike loma. Data ...
Analiza uticaja geometrije i heterogenosti zavarenog spoja na ponašanje Šarpi epruvete / The analysis of geometry and welded joint heterogeneity effect on Charpy specimen behaviour
(Institut za ispitivanje materijala, Beograd, 2003)
U radu je analiziran uticaj geometrije (oblik zareza, dimenzije epruvete) i heterogenosti materijala (mismečing zavarenog spoja) na ponašanje Šarpi epruvete. Primenjena je dvo- i trodimenzionalna naponska analiza metodom ...
Procena integriteta zavarene konstrukcije oblika ploče sa prslinom / Structural integrity assessment of welded plate with a crack
(Institut za ispitivanje materijala, Beograd, 2004)
Analiziran je uticaj geometrije (položaj prsline, dimenzije i oblik zavarenog spoja, dimenzija uzorka) i heterogenosti materijala na ponašanje i ocenu integriteta zavarenih ploča. Eksperimentalnom analizom obuhvaćene su ...
Plane strain fracture toughness of MP35N in aged and unaged conditions measured using modified CT specimens
(Elsevier Science Sa, Lausanne, 2003)
The multiphase alloy MP35N (35% Ni, 35% Co, 10% Mo, 20% Cr) is a high strength, high toughness alloy of choice for several safety-critical applications in aerospace, oil drilling, and biomedical industries. Several previous ...
