Economic Implications of Innovative Visual Guidance System for Crane Cabins
(Springer, 2020)
This paper proposes innovation through implementation of a real-time computer-aided visual guidance system (VGS) which prevents crane accidents, caused by crane operator’s obstructed view, which can be the cause of collisions ...
Load and deformation effects on brittle fracture of ferritic steel 20МnМoНi 55 in temperature transition region
(Institut za ispitivanje materijala, Beograd, 2020)
It is known that the load level, the way deformation is applied and the level of plastic strain, all can 'aid' or 'hinder' the occurrence of brittle fracture, but the question is - to what extent? These influential factors ...
Impact of Aging Effect and Heat Treatment on the Tensile Properties of PLA (Poly Lactic Acid) Printed Parts
(Revista Chimie Srl, Bucuresti, 2020)
Rapid innovations in 3D printing technology have allowed highly complex parts to be manufactured quickly and easily, particularly for prototyping purposes. Fused Deposition Modeling of thermoplastic materials is one of the ...
Comparison of experimental, numerical and analytical risk assessment of oil drilling rig welded pipe based on fracture mechanics parameters
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Fracture mechanics parameters are used for experimental, numerical and analytical risk assessment of structural integrity and life of oil drilling rig welded pipe with a crack. As a simple analytical tool, the Failure ...
Application of Fracture Mechanics Parameters to Spherical Storage Tank Integrity Assessment
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Fracture mechanics parameters have been applied to assess pressure vessel integrity. The pressure vessel analysed here was the ammonia spherical tank (volume of 1800 m(3), outer diameter 15.12 m, thickness 30 mm) where ...
Ekonomska opravdanost kabina kranova opremljenih računarskim sistemom vizuelnog navođenja u realnom vremenu / The economic feasibility of crane cabins with real-time computer-aided visual guidance system
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2020)
Brojna istraživanja u oblasti nesreća u kojima učestvuju dizalice ukazuju na činjenice da je rad rukovaoca/kraniste posao visokog rizika i da je uzrok nesreća i nezgoda najčešće ljudski faktor. Shodno tome, inovacije na ...
Turbulence recognition in free convective flow by thermal-video post-processing in the case of a thermal power plant mill
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
This paper presents a study of a free convection flow around the walls of a ventilation mill of the Thermal Power Plant "Kostolac B", Kostolac, Serbia. A combined method consists of thermography and software post-processing, ...
Determination of the optimal production plan by using fuzzy AHP and fuzzy linear programming
(IOS Press, Amsterdam, 2020)
In this paper, we consider the problem of determining the optimal production quantity under uncertainties. The treated problem has a critical effect on the achievement of business goals, which further propagates to the ...
XFEM based analysis of fatigue crack growth in damaged wing-uselage attachment lug
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The research presented in this paper is based on the use of extended finite element method (XFEM) for stress intensity factors (SIFs) determination in the case of fatigue crack presented in the wing-fuselage attachment lug ...
Structural Integrity Assessment of Welded Pipeline Designed with Reduced Safety
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
The main goal of this paper was to assess the integrity of welded joints in the main pipeline of the reversible hydropower plant "Bajina Bata". Japanese steel Sumiten 80P (SM 80P) was used as the parent material. European ...
