Numerical analysis of different weld geometries of lap welded joint in ammonia transport tanks
(Institut za ispitivanje materijala, Beograd, 2017)
Presented is a comparison of stress and strain distribution in lap welded joints of different geometries, which are part of a pressure vessel used as an ammonia transport tank. For this purpose, two numerical models are ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
Numerical analysis of stress distribution in total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2017)
Total hip replacement implants represent permanent implants and require large bone and cartilage removal during implantation. Revision would affect joint capability to sustain load, which makes this procedure irreversible. ...
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 ...
