Ponašanje legure Al-Mg frikciono zavarene mešanjem pri udarnom lomu / Impact fracture response of friction stir welded Al-Mg alloy
(Institut za ispitivanje materijala, Beograd, 2013)
Ispitivani su uticaji parametara frikcionog zavarivanja mešanjem na ponašanje loma udarom po Šarpiju u leguri Al-Mg 5083. Rotaciona i poprečna brzina zavarivanja su povezane sa dinamičkom inicijacijom prsline i duktilno ...
Aerodynamic design and analysis of a small-scale vertical axis wind turbine
(Korean Soc Mechanical Engineers, Seoul, 2013)
Small-scale vertical axis wind turbines are regarded today as an attractive source of green energy, still insufficiently implemented and tested. This paper presents a fast design methodology of such a VAWT, in terms of ...
Scenario razvoja loma u rotorskom bageru / Scenario of fracture development in bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2013)
Produženi rad rotorskog bagera (BWE) u teškim radnim uslovima može dovesti do otkaza mašina. Kod veoma važnih elemenata konstrukcije, može dovesti do katastrofalnog loma. Lociranje važnih elemenata konstrukcije je od ...
