Failure analysis of bicycle frame composite structure based on stacking variant of laminate layers
(Institut za ispitivanje materijala, Beograd, 2020)
No matter what kind of bike the parts belong to (according to the requirements they need to meet), these parts are almost identical. The most complex bicycle part in the structural optimization for manufacture is a bicycle ...
Numerical simulation of welded joint with multiple various defects
(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents continuation of extensive work on determining the behaviour of welded joints in the presence of multiple various types of defects, a problem that is not sufficiently covered by existing standards, such ...
Repair welding procedure and techno-economic analysis of burner pipe
(Institut za ispitivanje materijala, Beograd, 2021)
The selection of the electrode for repair welding is one of the activities needed before repairing machine parts. In this case, damages that have occurred in a burner pipe welded joint during manufacture or previous repair ...
Finite element analysis of spherical storage tank stress state
(Institut za ispitivanje materijala, Beograd, 2021)
In this paper, a spherical storage tank for the storage of liquefied petroleum gas is analysed. A design calculation of structural elements is performed according to valid standards and technical regulations. Seismic loads ...
Fatigue life analysis of the integral skin-stringer panel using xfem
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue life of integral skin-stringer panels produced by laser beam welding (LBW) is analysed. This type of panel is used in airframe construction where fatigue and damage tolerance are of paramount importance, since ...
Impact of temperature and exploitation time on plane strain fracture toughness, k-ic, in a welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents the analysis of the impact of temperature and exploitation time on the tendency toward brittle fracture of welded joint constituents of new and exploited low-alloyed Cr-Mo steel A-387 Gr. B, by using ...
Simulation of fatigue crack growth in a2024-t351 t-welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue crack growth in friction stir welded T joints under three point bending is simulated numerically using the Extended Finite Element Method (XFEM). Three point bending fatigue load stress is applied at the centre of ...
Expectations, reality and perspectives in using bim for the green building design
(Institut za ispitivanje materijala, Beograd, 2017)
In the late 1970s when the first programs for building energy consumption simulation appeared, architectural practice was based on paper documentation and 2D drafting programs were considered as state of the art technologies. ...
Cracking due to repair welding of the treiber roll
(Institut za ispitivanje materijala, Beograd, 2017)
Repair welding has caused crack initiation in the upper Treiber roll in the steel works plant mill at Zelezara in Smederevo. The upper and lower Treiber rolls serve the purpose of folding and directing rolled metal strips, ...
Remaining life determination for pressure vessel in a refinery
(Institut za ispitivanje materijala, Beograd, 2016)
Repair and inspection has been performed on a pressure vessel in the oil refinery for downstream treatment of crude oil in Iraq, without technical documentation. Two different approaches have given totally different results ...
