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 ...
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. ...
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 ...
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 ...
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. ...
Design and manufacture of reformer in polymer electrolyte membrane fuel cell
(Institut za ispitivanje materijala, Beograd, 2017)
The paper describes the development and manufacturing aspects of the reformer in polymer electrolyte membrane (PEM) fuel cell, from the first step of realization that includes modelling the main parts of the reformer; ...
