Presence of crack due the constant exploitation of turbine shaft
(Advanced Technologies & Materials, 2023)
Designing, constructing and putting into operation a hydroelectric power plant includes complex
tasks. Stresses of turbine and hydromechanical equipment of hydro power plants arise during the
production of parts and ...
The Finite Element Method in the function of corrosion damage assessment of pipelines
(SERBIAN SOCIETY OF CORROSION AND MATERIALS PROTECTION (UISKOZAM), 2023)
Pipelines, with specifics in design, construction, testing and safety requirements must be designed
based on all relevant influences to ensure that they are safe during their working life. Allowable
stresses must be ...
Effects of Alloying Elements on the Properties of HSLA Steel
(University of Belgrade - Faculty of Mechanical Engineering, 2023)
The first industrial application of elevated and high-strength steel in the form of hot-rolled strips and sheets
was the manufacture of pipes and vessels under pressure, as it was possible to reduce the thickness, i.e. ...
Type of precipitation and durations of sediment exposure as important weathering factors
(Elsevier, 2023)
A diversity of factors, led by lithology, weathering, and erosion processes, plays a significant role in the formation and future of badland terrains. Then on previous observations it can be concluded that surface flow ...
Influence of Aggregate Type on the Properties on SCC with Fly Ash
(International RILEM Conference on Synergising Expertise towards Sustainability and Robustness of Cement-based Materials and Concrete Structures, 2023)
This study compared the performance of self-compacting concrete (SCC) based on fly ash addition and limestone filler. A SCC prepared with Portland cement, river sand, and limestone filler was used as a reference sample. ...
Life assessment using the finite element method of high-strength low-alloy steel samples exposed to low-cycle fatigue
(16th International Conference on Accomplishments in Mechanical and Industrial Engineering DEMI, 2023)
In the paper, based on the results of experimental research on the behavior of samples in the form of
round smooth test specimens (STS) made of high strength low alloy steel (HSLA), Nionikral 70 (NN
70), under conditions ...
Occurrence of cracks due to inadequate turbine shaft construction
(16th International Conference on Accomplishments in Mechanical and Industrial Engineering DEMI, 2023)
After several decades of constant exploitation of the horizontal bulb turbine, which is an integral
part of the hydroelectric power unit, empirically, the formation of a crack occurs in the turbine shaft
due to the ...
Procedures for preventing corrosion of welded joints
(SERBIAN SOCIETY OF CORROSION AND MATERIALS PROTECTION (UISKOZAM), 2023)
This paper describes the procedures for preventing corrosion of welded joints. Also, a theoretical
overview of the forms of corrosion that are most prevalent in welded joints is presented.
The concept of corrosion in ...
European Directives Through the Integrity Evaluation of the Mechanical Equipment
(International Journal of Manufacturing Economics and Management, 2023)
Hydroelectric generating units at hydro power plants consist of turbine and hydromechanical equipment, which components could be subject to a large number of European Directives. Responsibility of turbine manufacturer is ...
