Manufacturing parameter influence on FDM polypropylene tensile properties
(Journal of Mechanical Science and Technology, 2023)
Polypropylene (PP) is a relatively new material in fused deposition modeling (FDM) technology. The main feature of this material is its ability to significantly elongate under applied load, unlike any other thermoplastic ...
Rectified ethanol production cost analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, ...
Damage Level Estimate of API J55 Steel for Welded Seam Casing Pipes
(Croation Union of Mech. Engineers and Naval Architects, 2009)
The subject of this paper is investigation of the damage level of API J55 steel, used for manufacturing casing pipes by high frequency (HF) contact welding. The analysed pipe was withdrawn after about 70 000 hours of service ...
Thermal history and stress state of a fresh steam-pipeline influencing its remaining service life
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
The service life of thick-walled power plant components exposed to creep, as is the case with pipelines of fresh- and reheated steam, depend on the exhaustion rate of the material. Plant operation at elevated temperatures ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
Ductile fracture prediction of steam pipeline steel
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Considering the conditions to which steels used for the manufacture of steam pipelines are exposed, the micromechanism of their destruction in exploitation is exclusively the ductile one. In order to make an estimation of ...
Environmental, social and other non-profit impacts Of mountain streams usage as Renewable energy resources
(Technical Institute of Bijeljina Republic of Srpska - Bosnia and Herzegovina, 2023)
The main subject of this manuscript is mountain streams used by construction of small hydro power plants. The motivation for this research stemmed from a number of conflicting opinions about the justification of the ...

To address the question of weather stands are managed sustainably in the Novi Pazar region (Southwest Serbia), this study compares the quantity of standing wood biomass in the Debeljak-Medenovac unit at the beginning and ...
Influence of Mechanical Activation of a Cordierite –Based Filler on Sedimentation Stability of Lost Foam Refractory Coatings
(Science of Sintering, 2019)
For the development of the Lost Foam refractory coatings with controlled rheologic properties, the influence of the mechanical activation process on the cordierite-based filler's properties change was examined. First of ...
The influence of material infill on ABS-X flexural strength
(Springer, 2023)
This paper contains a comparison of the flexural strength results of two different samples. Both samples were made using additive manufacturing, from ABS (acrylonitrile butadiene styrene) material with the inclusion of an ...
