Structural integrity assessment from the aspect of fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2019)
An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in ...
Integrity assessment of reverse engineered ti-6al-4v eli total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2019)
Total hip replacement implants are used as an artificial replacement for disfunctional hips in order to sustain joint movement. Chosen material and design of total hip replacement are the most influential factors for ...
Repair of cracks detected in cast components of vertical kaplan turbine rotor hub
(Institut za ispitivanje materijala, Beograd, 2019)
During the revitalization of the hydroelectric generating station A4 at the hydro power plant 'Djerdap 1', all of its parts are subjected to non-destructive testing. Cracks are detected in cast part of generator rotor hub, ...
Faktori sigurnosti u proračunu debljine zida kolona za rektifikaciju / Safety factors in wall thickness calculation of rectification columns
(Vojnotehnički institut, Beograd, 2021)
Kolone za rektifikaciju gasa veoma su važan deo svake fabrike. Njihovi iznenadni otkazi svakodnevno uzrokuju ogromne gubitke, dok curenje tečnosti može biti veoma opasno po ljude i životnu sredinu. Iz tog razloga, pravilan ...
Creep crack growth behavior of p91 steel weldments
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i. e. secondary creep process. Therefore, creep crack growth tests were ...
Integration of solar energy by nature-inspired optimization in the context of circular economy
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The purpose of this paper is to make a research on solar power plants integration in an electric power system, taking into account all costs arising from circular economy criteria. Four scenarios of solar power plant ...

Inovativna tehnologija laserskog čišćenja različitih površina u industriji, uključuje integrisani pristup kontrole procesa interakcije laser-materijal i ispitivanja rezultata laserskog delovanja. Lasersko čišćenje ima ...
Effect of laser beam welded reinforcement on integral skin panel fatigue life
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, numerical analyses of fatigue crack growth in integral skin-stringer panel produced by means of laser beam welding (LBW) are presented along with fatigue results verified by previously conducted experiments. ...
Effects of a low-Shrinkage methacrylate monomer and monoacylphosphine oxide photoinitiator on curing efficiency and mechanical properties of experimental resin-based composites
(Elsevier, Amsterdam, 2016)
This study investigated the degree of conversion, depth of cure, Vickers hardness, flexural strength, flexural modulus and volumetric shrinkage of experimental composite containing a low shrinkage monomer FIT-852 (FIT; ...
Total costs of shell and tube heat exchangers with concentric helical tube coils
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The paper deals with the manufacturing costs of shell and tube heat exchangers with concentric helical tube coils. The most common correlations for calculating prices of shell and tube heat exchangers found in accessible ...
