Numerical analysis of geometric characteristics of mandible fixation plates made of hydroxyapatite structures
(Institut za ispitivanje materijala, Beograd, 2019)
Bone defect reparation can be successfully performed with biomaterials based on synthetic hydroxyapatite (HA). In addition to collagen, hydroxyapatite is the basic structure of bone tissue and it is expected to have excellent ...
Radionuclide Immobilization by Sorption onto Waste Concrete and Bricks-Experimental Design Methodology
(Springer International Publishing Ag, Cham, 2019)
The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that ...
The Effect of Vanadium Content on Microstructure and Impact Toughness of Forged High Alloy Steel X96CrMo12-1
(Springer International Publishing Ag, Cham, 2019)
The aim of this research was to examine the influence of vanadium on the structure and impact toughness of the forged high alloy steel X96CrMo12-1. It is known that vanadium affects the process of solidification of this ...
Probabilistička analiza uređaja za razdvajanje odnosa naponskog razdelnika / Probabilistic analysis of voltage divider ratios
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Tolerancija modernih otpornika obično varira od 0.1% do 1 %. Sa probabilističke tačke gledišta to znači da se odgovarajući otpor može posmatrati kao slučajna promenljiva sa odgovarajućom funkcijom gustine raspodele verovatnoće ...
Numerical-Experimental Determination of Stress and Deformation State in Connecting Lugs with the Effect of Contact Area Size
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
The present paper describes numerical and experimental methodology for the analysis of stress and deformation state in structural elements with geometrical discontinuities. The research is based on structural elements of ...
Design aspects of light aircraft wing spar—Differential and integral approach
(John Wiley and Sons Inc, 2019)
Three different wing spar designs (differential, equivalent integral, and optimized integral) are analysed, in order to establish the optimum one. Numerical analysis was carried out by extended finite element method (XFEM) ...
Integrity assessment and determination of residual fatigue life of vital parts of bucket-wheel excavator operating under dynamic loads
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper are presented results of tests and analyses of complex dynamic loads carried out on the bucket-wheel excavator SchRs 650/5x24 Krupp, as well as assessment of service life of vital welded structures of a ...
Efficiency and power upgrade at the aged lignite-fired power plant by flue gas waste heat utilization: High pressure versus low pressure economizer installation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A substantial potential exists for the recovery of flue gas waste heat at aged coal-fired power plants. High and low pressure economizers (HPE, LPE) can be applied for this purpose. Two cases of the feedwater supply to the ...
