Description
Presents a systematic view of vibro-impact dynamics based onthe nonlinear dynamics analysis
Comprehensive understanding of any vibro-impact system iscritically impeded by the lack of analytical tools viable forproperly characterizing grazing bifurcation. The authors establishvibro-impact dynamics as a subset of the theory of discontinuoussystems, thus enabling all vibro-impact systems to be explored andcharacterized for applications.
Vibro-impact Dynamics presents an original theoreticalway of analyzing the behavior of vibro-impact dynamics that can beextended to discontinuous dynamics. All topics are logicallyintegrated to allow for vibro-impact dynamics, the central theme,to be presented. It provides a unified treatment on the topicwith a sound theoretical base that is applicable to both continuousand discrete systems
Vibro-impact Dynamics:
* Presents mapping dynamics to determine bifurcation and chaos invibro-impact systems
* Offers two simple vibro-impact systems with comprehensivephysical interpretation of complex motions
* Uses the theory for discontinuous dynamical systems ontime-varying domains, to investigate the Fermi-oscillator
Essential reading for graduate students, university professors,researchers and scientists in mechanical engineering.

Professor Luo is currently a Distinguished ResearchProfessor at Southern Illinois University Edwardsville. He is aninternational renowned figure in the area of nonlinear dynamics andmechanics. For about 30 years, Dr. Luo's contributions onnonlinear dynamical systems and mechanics lie in (i) the localsingularity theory for discontinuous dynamical systems, (ii)Dynamical systems synchronization, (iii) Analytical solutions ofperiodic and chaotic motions in nonlinear dynamical systems, (iv)The theory for stochastic and resonant layer in nonlinearHamiltonian systems, (v) The full nonlinear theory for a deformablebody. Such contributions have been scattered into 13 monographs andover 200 peer-reviewed journal and conference papers. His newresearch results are changing the traditional thinking in nonlinearphysics and mathematics. Dr. Luo has served as an editor for theJournal "Communications in Nonlinear Science and Numericalsimulation", book series on Nonlinear Physical Science (HEP)and Nonlinear Systems and Complexity (Springer). Dr. Luo is theeditorial member for two journals (i.e., IMeCh E Part K Journal ofMultibody Dynamics and Journal of Vibration and Control). He alsoorganized over 30 international symposiums and conferences onDynamics and Control.
