Weibull probability distribution for reactor steel 20MnMoNi55 cleavage fracture in transition temperature
(Elsevier, Amsterdam, 2020)
This paper presents the results and methods used for determining of fracture toughness of reactor steel, denoted as 20MnMoNi55, typically used for structures working at low temperatures, in transition temperature area. In ...
Dual Phase Austempered Ductile Iron - The Material Revolution and Its Engineering Applications
(Springer International Publishing Ag, Cham, 2020)
During the last few years, there has been an increased interest in improving the strength of ductile iron by means of heat-treating to obtain dual phase microstructures that enhance the properties found in the Austempered ...
Laser Processing of Ni-Based Superalloy Surfaces Susceptible to Stress Concentration
(MDPI, Basel, 2021)
Reliable and resilient constructions are basic for ensuring the safety of various structures. The superalloys are used as constructive materials due to their superb mechanical properties and endurance. However, even these ...
Numerical evaluation of thermal stresses generated in laminated composite structure exposed to low temperatures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
This paper presents numerical calculation of thermal stresses generated in a carbon fiber-epoxy laminated composite structure which is operating at low temperatures. The thermal stress evaluation is based on the finite ...
Stress Analysis of a Pipeline as a Hydropower Plant Structural Element
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2020)
This paper describes pipeline stress analysis, primarilybranch junctions, as a structural element in hydro-power plants. Pipelines are exposed to internal pressure,which is present under working conditions. Analysis of ...
Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
Nonlinear Dynamics as a Tool in Selection of Working Conditions for Radial Ball Bearing
(Springer, 2020)
This paper contains elements of a comprehensive research devoted to the dynamic behavior of radial ball bearings in real working conditions. The general motivation for this topic comes from the requirements for high ...
Experimental and numerical methods for concept design and flow transition prediction on the example of the bionic high-speed train
(Springer, 2021)
In the times of significant development of high-speed train transportation and taking the primacy over the others, one of the major designing tasks is to predict accurately and fast the vehicle’s main performances, especially ...
Numerical simulation of welded joint with multiple various defects
(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents continuation of extensive work on determining the behaviour of welded joints in the presence of multiple various types of defects, a problem that is not sufficiently covered by existing standards, such ...
Thermalhydraulics of once-through steam boiler tubes revisited
(Department of Thermal Technology, Gliwice, Poland, Silesian University of Technology 2020, 2020)
The analysis of pressure changes in water and steam flow along the entire once-through steam boiler
tube system was carried out. An efficient advanced method is developed and presented for the
prediction of once-through ...
