Contribution to the determination of the global minimum time for the brachistochronic motion of a holonomic mechanical system
(Springer, Dordrecht, 2017)
The problem of the brachistochronic motion of a holonomic scleronomic mechanical system is analyzed. The system moves in an arbitrary field of known potential forces. The problem is formulated as an optimal control task, ...
Investigation into the causes of fracture in railway freight car axle
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Railway axles are vital parts of railway. Their failure in the form of dynamic fracture is commonly of disastrous outcomes for railway vehicles. Accordingly, railway axles are designed to be highly reliable, while the ...
Calculation of the Heat Transfer Coefficient for Laminar Flow in Pipes in Practical Engineering Applications
(Taylor & Francis Inc, Philadelphia, 2018)
Paper presents an analysis of existing correlations for laminar liquid flow and heat transfer in tubes based on the published theoretical research and experimental data. Considering the relatively large deviation of existing ...
Failure analysis of a special vehicle engine connecting rod
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
This paper presents failure analysis of the connecting rod used in a 12-cylinder diesel engine set on a special vehicle. The fracture of the connecting rod occurred during the engine test in laboratory conditions. Chemical ...
Novel fractal analysis of nanograin growth in BaTiO3 thin film
(Elsevier Science Sa, Lausanne, 2020)
The grain size and the ferroelectric morphology are the two most important factors in the research and development of advanced dielectric devices. It is important to synthesize nanostructures in order to achieve optimal ...
Assessment of corroded API 5L X52 pipe elbow using a modified failure assessment diagram
(Elsevier Sci Ltd, Oxford, 2021)
Pipe elbows (bends) are considered critical pressurized components in the piping systems and pipelines due to their stress intensification and the effect of bend curvature. They are prone and hence more exposed to different ...
Coupled bending and axial vibrations of axially functionally graded Euler-Bernoulli beams
(Springer, 2023)
Purpose This study aims to obtain and present the closed-form solution of coupled
axial-bending vibration problem for the general case of axially functionally graded
(AFG) beams, to create the frequency equation and to ...
