Izvijanje cilindrične tankozide strukture izrađene od legure aluminijuma sa greškom u geometriji u vidu udubljenja, pod dejstvom aksijalnog pritiska / Buckling behaviour of dented aluminium alloy cylindrical shell subjected to uniform axial compression
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Tankozide cilindrične strukture imaju veoma visoku primenu u industriji. Pošto su obično opterećene na aksijalni pritisak, najčešći uzrok njihovog otkaza je pojava izvijanja. U ovom članku se prikazuje numerička analiza ...
Integrity assessment of vital beam components that enable conjoint operation of two bridge cranes
(Institut za ispitivanje materijala, Beograd, 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 ...
