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 ...
Organizaciona kultura i unapređenje kvaliteta - razlike između kontinenata / Organizational culture and quality improvement: Differences across continents
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2020)
Prethodna istraživanja pokazuju da organizacioni faktori utiču na programe unapređenja kvaliteta, na način da su performanse preduzeća bolje kada postoji usaglašenost između navedenih faktora. Stoga je cilj ovog rada analiza ...
Integrity assessment of ammonia storage tank by non-destructive testing
(Institut za ispitivanje materijala, Beograd, 2021)
Ammonia is a very dangerous fluid, and it is so important that its storage tanks are safe. Fusion welded joints (in further text: welded joints) are the 'weakest' location in some structures, in this case - tanks, and the ...
Novel procedure to determine actual stress-strain curves
(Institut za ispitivanje materijala, Beograd, 2021)
This paper presents a novel procedure for determining the actual stress- strain curves for undermatching rectangular welded joints made of martensitic armoured steel Armox 500T. The method is based on an analytical expression ...
Integrity of Welded Joints Made of Alloy NiCr21Mo
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
The research covers the investigation of mechanical properties of welded joint made on NiCr21Mo alloy (commercial trademark Incoloy 825), and joints of steels P355GH and X2CrNiMo17-12-2, as well as the influence of the ...
Corrosion effect on mechanical properties of aluminium alloys 2024-t351 and 7075-t651
(Institut za ispitivanje materijala, Beograd, 2021)
Results of static tensile testing of aluminium alloys 2024T351 and 7075-T651 are presented with different levels of corrosion exposure in the laboratory environment. Specimens from two different rolling directions are ...
Influence of the polymer matrix type on cavitation resistance of composites
(Advanced Technologies & Materials, 2021)
Cavitation resistance of polymer matrix / basalt powder composites was determined in this work. Two types of composites
were tested: epoxy resin / basalt powder composite and polyester resin / basalt powder composite. In ...
SIZE EFFECT ASSESSMENT OF KJc EXPERIMENTAL DATA USING THE TWO-STEP-SCALING METHOD
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
The phenomenon of ductile-to-brittle transition (DBT) in ferritic steels, widely used in design of nuclear reactor pressure vessels, has been a pervasive semi-centennial research topic. Due to the extremely pronounced ...
New types of protective coatings and development of test methods
(Structural integrity and life, 2023)
The paper presents the results of synthesis and charac-terisation of refractory coatings based on various fillers intended for the protection of metallic structures. Refractory fillers applied are based on mullite, cordierite, ...
INSPECTION OF DAMAGE AND RISK ANALYSIS OF CONTAINERS IN A COAL DRYING FACILITY IN EXPLOITATION
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
Risk analysis of containers in a coal drying facility was performed using the Failure Modes and Effects Analysis (FMEA) method in combination with the risk matrix. The selected exploitation period analysed for all vessels ...
