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 ...
Nonlinear vibration of a nonlocal functionally graded beam on fractional visco-Pasternak foundation
(Springer, Dordrecht, 2022)
This paper investigates the nonlinear dynamic behavior of a nonlocal functionally graded Euler-Bernoulli beam resting on a fractional visco-Pasternak foundation and subjected to harmonic loads. The proposed model captures ...
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 ...
On the problem of a heavy homogeneous ball rolling without slipping over a fixed surface of revolution
(Elsevier Science Inc, New York, 2022)
The paper considers a heavy homogeneous ball rolling without slipping on the outside of a real rough fixed surface of revolution, which is generated by rotating a plane curve around a vertical axis. By applying the Coulomb ...
Mass minimization of an Euler-Bernoulli beam with coupled bending and axial vibrations at prescribed fundamental frequency
(Elsevier Sci Ltd, Oxford, 2021)
The problem of determining the optimum shape of a homogeneous Euler-Bernoulli beam of a circular cross-section, in which the coupled axial and bending vibrations arose due to complex boundary conditions, is considered. The ...
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 ...
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 ...
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 ...
