Non-homogeneity effect in the spherical shell by using seth's theory
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents nonlinear deformation behaviour of non-homogeneous spherical shell examined under pressure by using Seth's transition theory. It has been seen that for increased material compressibility in thickness ...
Analysis of fracture behaviour of thin s316l stainless steel plates
(Institut za ispitivanje materijala, Beograd, 2017)
In this paper are presented experimental analyses of the behaviour of 316L stainless steel in regard to fracture, according to standard methods of investigation on modified tensile C(T) specimens. The S316L alloy is selected ...
Numerical assessment of stress intensity factors at tips of multi-site cracks in unstiffened panel
(Institut za ispitivanje materijala, Beograd, 2017)
The aim of this paper is to establish and demonstrate diverse capacity and performances of different numerical methods for calculating stress intensity factors' (SIFs) histories versus crack length for problems involving ...
Numerical analysis of heat transfer during friction stir welding
(Institut za ispitivanje materijala, Beograd, 2017)
The paper deals with the heat input and maximum temperature that develops in friction stir welding with different welding parameters. The finite element method has been used for numerical analysis of temperature distribution ...
Uključenost zaposlenih kao faktor fleksibilnosti privrednih društava u Republici Srbiji - empirijsko istraživanje / The involvement of employees as a flexibility factor of companies in the Republic of Serbia: Empirical research
(Ekonomski institut, Beograd, 2017)
Adekvatno i pravovremeno reagovanje u uslovima stalnih promena od suštinskog je značaja za opstanak kompanije. Kapacitet za takvo reagovanje se meri stepenom fleksibilnosti pri čemu se pod fleksibilnošću podrazumeva ...
Low-temperature corrosion damage and repair of boiler bottom panel tubes
(Institut za ispitivanje materijala, Beograd, 2017)
The method used for repairing of the bottom panel of hot water boiler of 30 MW power, manufactured by Remming (a part of the 'Valjevo' Heating Plant) is presented in this paper along with the reasons why damage has occurred. ...
Influence of Friction Welding Parameters on Properties of the Al-Cu Joint
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
In this paper is presented a theoretical-experimental analysis of the aluminum-copper joining by friction welding. Considering that such Al-Cu bimetal joints are widely applied in industrial practice, experimental analysis ...
Izvijanje cilindrične tankozide strukture izrađene od legure aluminijuma sa greškom u geometriji u vidu udubljenja, pod dejstvom aksijalnog pritiska / Buckling behaviour of dented aluminium alloy cylindrical shell subjected to uniform axial compression
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Tankozide cilindrične strukture imaju veoma visoku primenu u industriji. Pošto su obično opterećene na aksijalni pritisak, najčešći uzrok njihovog otkaza je pojava izvijanja. U ovom članku se prikazuje numerička analiza ...
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. ...
Fatigue life estimation of cct specimen using xfem
(Institut za ispitivanje materijala, Beograd, 2017)
In this study a central crack tension (CCT) specimen is chosen for analysis to demonstrate the capability and reliability of the extended finite element method (XFEM) in predicting the crack propagation trajectory and ...
