Predviđanje veka čeličnog žičanog užeta u eksploataciji / Service life prediction of running steel wire ropes
(Institut za ispitivanje materijala, Beograd, 2010)
Vrlo visoka čvrstoća omogućava žičanom užetu da prenese velike zatezne sile i da se kreće po koturima relativno malog prečnika. Žice od čelika vrlo visoke čvrstoće su postojale više od sto godina pre nego što su patentirane, ...
Procena integriteta konstrukcije implanta veštačkog kuka izrađenog od višefazne Co-Cr legure / Structural integrity assessment of hip implant made of cobalt-chromium multiphase alloy
(Institut za ispitivanje materijala, Beograd, 2010)
Rad prikazuje analizu parametara mehanike loma višefazne Co-Cr legure, koja se koristi kao materijal za implant kod ugradnje veštačkog kuka. Konstrukcijski parametri koje bi trebalo uzeti u obzir tokom projektovanja implanta ...
Numericko-eksperimentalna dijagnostika cvrstoce konstrukcija / Numerical and experimental diagnostics of structural strength
(Institut za ispitivanje materijala, Beograd, 2010)
The paper presents developed procedure of numerical and experimental diagnostics of structural strength. Numeri-cal diagnostics uses finite elements method, calculated results analysis and behaviour parameters definition. ...
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 ...
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 ...
Uticaj zone loma iznad podzemne prostorije na opterećenje konstrukcije sa visećom podgradom / Impact of a failure zone above the underground roadway on rockbolting structure loading
(Institut za ispitivanje materijala, Beograd, 2015)
Research in this article presents development of model of strata interaction with roof support installed in bauxite. The main task of this research is modelling of rock degradation over the surface of underground roadway ...
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 ...

Analysed are the developments of military equipment and the impact of Mihailo Petrovic's inventions on them. Great contribution from the works of our scientists and inventors to the development of world science in the late ...
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 ...
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 ...
