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 ...
A new approach for the determination of the global minimum time for the Chaplygin sleigh brachistochrone problem
(Sage Publications Ltd, London, 2017)
A new approach for the determination of the global minimum time for the case of the brachistochronic motion of the Chaplygin sleigh is presented. The new approach is based on the use of the shooting method in solving the ...
Free vibration of structures composed of rigid bodies and elastic beam segments
(Academic Press Ltd- Elsevier Science Ltd, London, 2015)
Free vibration of structures composed of rigid bodies and elastic beam segments is considered, assuming that the mass centers of rigid bodies are not located on the neutral axes of undeformed elastic beam segments. It is ...
Free vibration analysis of axially functionally graded tapered, stepped, and continuously segmented rods and beams
(Elsevier Sci Ltd, Oxford, 2018)
In this paper a new non-iterative computational technique referred to as the symbolic-numeric method of initial parameters (SNMIP) is proposed. The SNMIP represents a modification of the iterative numeric method of initial ...
First passage of stochastic fractional derivative systems with power-form restoring force
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this paper, the first-passage failure of stochastic dynamical systems with fractional derivative and power-form restoring force subjected to Gaussian white-noise excitation is investigated. With application of the ...
Chaotic fruit fly optimization algorithm
(Elsevier, Amsterdam, 2015)
Fruit fly optimization algorithm (FOA) is recently presented metaheuristic technique that is inspired by the behavior of fruit flies. This paper improves the standard FOA by introducing the novel parameter integrated with ...
Active vibration control of smart composite plates using optimized self-tuning fuzzy logic controller with optimization of placement, sizing and orientation of PFRC actuators
(Academic Press Ltd- Elsevier Science Ltd, London, 2019)
This paper deals with optimization of the sizing, location and orientation of the piezo-fiber reinforced composite (PFRC) actuators and active vibration control of the smart composite plates using particle-swarm optimized ...
The brachistochronic motion of a wheeled vehicle
(Springer, Dordrecht, 2017)
The paper considers the brachistochronic motion of a wheeled vehicle on a horizontal plane surface. The objective is to transfer the vehicle from the specified initial position with given initial kinetic energy to the ...
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 ...
Fractal frontiers in microelectronic ceramic materials
(Elsevier Sci Ltd, Oxford, 2019)
The world's perennial need for energy and microelectronic miniaturization brings with it a broad set of technological and scientific challenges. Materials characterized by precise microstructural architectures based on ...
