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 ...
Influence of temperature and exploitation period on the behaviour of a welded joint subjected to impact loading
(Institut za ispitivanje materijala, Beograd, 2016)
Presented in this paper is the analysis of the influence of temperature and exploitation period on the measure of fracture resistance of welded joint constituents in both new and exploited low-alloyed Cr-Mo steel A-387 Gr. ...
Influence of multiple defects in welded joints subjected to fatigue loading according to sist en iso 5817: 2014
(Institut za ispitivanje materijala, Beograd, 2018)
Structural integrity of pressure vessels is of great importance in ensuring their safe exploitation. Due to this, a number of standards are developed in order to define the criteria according to which materials, technologies ...
