Temperature dependent effective friction coefficient estimation in friction stir welding with the bobbin tool
(VINCA Institute of Nuclear Sciences, 2016)
The friction coefficient in many friction stir welding researches is generally used as an effective, constant value without concern on the adaptable and changeable nature of the friction during welding sequence. This is ...
Rapid pyrolysis of Serbian soft brown coals
(VINCA Institute of Nuclear Sciences, 2009)
Soft brown coals of the open coal fields of Kolubara and Kostolac are the main domestic energy sources of Serbia. This paper presents the results of investigations on rapid devolatilization of these two coals which have ...
Fine tuning of dwelling time in friction stir welding for preventing material overheating, weld tensile strength increase and weld nugget size decrease
(VINCA Institute of Nuclear Sciences, 2016)
After successful welding, destructive testing into test samples from Al 2024-T351 friction stir butt welds showed that tensile strength of the weld improve along the joint line, while dimensions of the weld nugget decrease. ...
Chemical and thermodynamic properties of Bombyx mori (domestic silk moth): Empirical formula, driving force, and biosynthesis, catabolism and metabolism reactions
(Society of Thermal Engineers of Serbia, 2023)
Biothermodynamics is a discipline which has developed intensely during the last 50 years. Thermodynamic properties have been reported for humans, animals, plants and microorganisms. However, this paper reports for the first ...
Effective Temperature Based Algorithm for Achieving Constant Quality Resistance Seam Weld
(Belgrade : Vinča Institute of Nuclear Sciences, 2021)
The resistance seam welding is a welding technique that is often used for the creation of the leak-tight welds. It is a technique where the weld is created as a set
of overlapping weld nuggets between the cylindrical ...
