U ovom radu prikazan je razvoj metoda za procenu nastanka i širenja zamornih prslina u cilju povećanja radnog veka i pouzdanosti mašinskih elemenata i mašinskih sistema u uslovima zamora. Detaljno je izložena i analizirana ...

U različitim vremenskim periodima dolazilo je do gubitka integriteta zavarenih konstrukcija zbog razvoja proizvodnih grešaka zavarenog spoja. Mehanizmi otkaza su bili različiti i uvek su predstavljali novo iskustvo, koje ...

This paper displays the usage of Theory of Critical Distances (TCD) in the prediction of high-cycle fatigue behaviour in machine parts and systems. It is possible to gain real overview of stresses of machine parts by Finite ...

The objective of this paper is to give a new viewpoint in contact fatigue prediction in the case of high-cycle fatigue. The presented research is based on up-to-date methods and multidisciplinary approach, and enables ...

Primena čelika visoke čvrstoće kod projektovanja zavarenih konstrukcija zahteva podatke o svojstvima istih pri različitim uslovima opterećenja. Zahvaljujući visokom naponu tečenja debljina zida može se smanjiti u poređenju ...

High-cycle contact fatigue is a localized phenomenon that occurs in highly stressed grains of the material on or under the contact region. The contact zones of tooth flanks for meshed gears are subjected to contact fatigue ...

This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft flange transition section. The case study of hydraulic turbine shaft failure is used as the basis for this research. ...

The fracture surface appearances are slowly changed through decade’s side by advantages in technology of steel production. Basic requirements for cleaner steels and lower energy consumption during production induce that ...

Turbine and generator rotors and shafts undergo high stresses during regular working life and, from a safety and operational aspect, are the most significant components of a power generation system. Depending on the ...

The contact fatigue is a localized phenomenon that occurs in highly stressed local zone of the material under the loaded contact region and as such is highly nonlinear problem. This phenomenon exists in almost all real ...
