Effects of welding technology on the occurrence of fracture in welded joints
(Elsevier Science Bv, Amsterdam, 2018)
Welded joints represent locations where failure is most likely to occur in welded structures. Welded joint failure depends on their vulnerability to crack initiation and growth. These factors are significantly influenced ...
Oxidation behavior during prolonged service of boiler tubes made of 2.25Cr1Mo and 12Cr1Mo0.3V heat resistance steels
(Elsevier Science Bv, Amsterdam, 2016)
During service of thermal power plant (TPP) units, different components are exposed to high temperature due to technological cycle of TPP unit. Service lifetimes of these components, especially boiler heating surfaces, may ...
Model analysis of complex structures - advantages of physical sub-scaled model testing and shortcomings in physical model production
(Elsevier Science Bv, Amsterdam, 2018)
The possibilities of testing real constructions strength are often limited, especially in case of large constructions. Testing on the model, instead of the actual construction, results in a great saving of money and time. ...

Influence of Geometry on Pressure and Velocity Distribution in Packed-bed Methanol Steam Reforming Reactor
(Amer Inst Physics, Melville, 2017)
The main tasks of this research is to propose several changes in the packed bed micro methanol steam reformer geometry in order to ensure its performance. The reformer is an integral part of the existing indirect internal ...
The influence of illumination parameters on the performances of color sorting machines
(Scientific Proceedings XII International Congress "Machines, Technologies, Materials" 2015, 2015)
The color recorded in the image is not an inherent value of observed object, because it is also influenced by the illumination properties, as well as geometry and surfaces of neighboring objects. Numerous studies have ...

Heat transfer and lubrication of turboshaft motor-reducer
(Institute of Physics Publishing, 2018)
Turboshaft engines, as the rule, contains gear transmission unit - reducer and belong to the group of drive systems with the name motor-reducer. These are the compact and autonomous assemblies for various applications. In ...
Wear simulation of the polymer based composite sliding bearings by means of ansys
(Faculty of Engineering, University of Kragujevac, 2019)
Polymer based composite sliding bearings are increasingly applied in many industries, due to their economic (usually low cost of production) and technical (good tribological properties) benefits. In order to predict their ...
Dynamic stability of high speed turboshaft engine with reducer
(Institute of Physics Publishing, 2018)
The dynamic behavior of machines which rotate at extreme high speeds is crucial for stable and long operation. In design process some dynamics calculation must be taken into account to avoid potential operation near resonance ...
