Energy balance method for solving nonlinear oscillators with non-rational restoring force
In this study, an extended energy balance method for solving nonlinear oscillators with non-rational restoring force has been presented. The classical energy balance methods cannot apply to solve nonlinear oscillators with non-rational restoring force. To overcome this difficulty, a laborious study is to be conducted to determine the solution technique that provides better results as well as requires minimum computational efforts. An example of complicated nonlinear oscillator with non-rational restoring force arising in the field of engineering and other disciplines has been provided. The accuracy of the approximate results has been compared with other existing results.
期刊介绍:
The purpose of this journal is to provide a medium of exchange for scientists engaged in applied sciences (physics, mathematical physics, natural, and technological sciences) where there exists a non-trivial interplay between mathematics, mathematical modelling of real systems and mathematical and computer methods oriented towards the qualitative and quantitative analysis of real physical systems.
The principal areas of interest of this journal are the following:
1.Mathematical modelling of systems in applied sciences;
2.Mathematical methods for the qualitative and quantitative analysis of models of mathematical physics and technological sciences;
3.Numerical and computer treatment of mathematical models or real systems.
Special attention will be paid to the analysis of nonlinearities and stochastic aspects.
Within the above limitation, scientists in all fields which employ mathematics are encouraged to submit research and review papers to the journal. Both theoretical and applied papers will be considered for publication. High quality, novelty of the content and potential for the applications to modern problems in applied sciences and technology will be the guidelines for the selection of papers to be published in the journal. This journal publishes only articles with original and innovative contents.
Book reviews, announcements and tutorial articles will be featured occasionally.
