Eksperimentalno istraživanje ponašanja zavarenih posuda pod pritiskom sa prslinom / Prslinom experimental investigation of cracked welded pressure vessel behaviour
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2000)
Direktno merenje J integrala je primenjeno na modelima posuda pod pritiskom, izrađenih od šavnih cevi od čelika X55. Ispitana su dva modela, jedan sa prslinom u metalu šava, drugi sa prslinom u ZUT. Poseban problem u ...
Ocena integriteta sfernog rezervoara / Integrity assessment of spherical storage tank
(Institut za ispitivanje materijala, Beograd, 2003)
Analiziran je integritet sfernih rezervoara za amonijak (zapremine 1000 m3, prečnika 12400 mm, debljina zida 30 mm), zato što su otkrivene prsline na liniji stapanja, dužine do 300 mm, različite dubine. Direktnim merenjem ...

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 ...
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 ...
Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...

Manufacturing ammonia storage tanks represents a very demanding and responsible task. The paper presents the methodology for manufacturing two ammonia storage tanks in Russia, along with all the necessary steps. The base ...
Structural Integrity Assessment of Welded Pipeline Designed with Reduced Safety
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
The main goal of this paper was to assess the integrity of welded joints in the main pipeline of the reversible hydropower plant "Bajina Bata". Japanese steel Sumiten 80P (SM 80P) was used as the parent material. European ...
Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
