Introduction To Impact Dynamics

Fundamental guidance—including concepts, models, and methodology—for better understanding the dynamic behavior of materials and for designing for objects and structures under impact or intensive dynamic loading This book introduces readers to the dynamic response of structures with important emphasis on the material behavior under dynamic loadings. It utilizes theoretical modelling and analytical methods in order to provide readers with insight into the various phenomena. The content of the book is an introduction to the fundamental aspects, which underpin many important industrial areas. These areas include the safety of various transportation systems and a range of different structures when subjected to various impact and dynamic loadings, including terrorist attacks. Presented in three parts—Stress Waves in Solids, Dynamic Behaviors of Materials Under High Strain Rate, and Dynamic Response of Structures to Impact and Pulse Loading—Introduction to Impact Dynamics covers elastic waves, rate dependent behaviors of materials, effects of tensile force, inertial effects, and more. The book also features numerous case studies to aid in facilitating learning. The strength of the book is its clarity, balanced coverage, and practical examples, which allow students to learn the overall knowledge of impact dynamics in a limited time whilst directing them to explore more advanced technical knowledge and skills. Considers both the dynamic behavior of materials and stress waves, and the dynamic structural response and energy absorption, emphasizing the interaction between material behavior and the structural response Provides a comprehensive description of the phenomenon of impact of structures, containing both fundamental issues of wave propagation and constitutive relation of materials, and the dynamic response of structures under impact loads Based on the authors’ research and teaching experience as well as updated developments in the field Introduction to Impact Dynamics is the perfect textbook for graduate and postgraduate students, and will work as a reference for engineers in the fields of solid mechanics, automotive design, aerospace, mechanical, nuclear, marine, and defense.

Studies of vibro-impact dynamics falls into three main categories: modeling, mapping and applications. This text covers the latest in those studies plus selected deterministic and stochastic applications. It includes a bibliography exceeding 1,100 references.

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.

This compendium of mathematical techniques for the modeling and simulation of high-velocity impacts presents the various analytical and experimental aspects of impact dynamics and describes the responses of a variety of materials and structures under impact. Coverage is extended beyond that of the author's Impact Dynamics and deals with new topics in impacts involving inert materials, including the dynamic response to energetic and inert materials. Treatment uses classical mechanics along with the conservation laws, combined with failure analysis.

The aim of this International Symposium on Dynamics of Vibro-Impact Systems is to provide a forum for the discussion of recent developments in the theory and industrial applications of vibro-impact ocean systems. A special effort has been made to invite active researchers from engineering, science, and applied mathematics communities. This symposium has indeed updated engineers with recent analytical developments of vibro-impact dynamics and at the same time allowed engineers and industrial practitioners to alert mathematicians with their unresolved issues. The symposium was held in Troy, Michigan, during the period October 1-3, 2008. It included 28 presentations grouped as follows: The first group comprises of nine papers dealing with the interaction of ocean systems with slamming waves and floating ice. It also covers related topics such as sloshing-slamming dynamics, and non-smooth dynamics associated with offshore structures. Moreover, it includes control issues pertaining to marine surface vessels. The second group consists of fifteen papers treats the interaction of impact systems with friction and their control, Hertzian contact dynamics, parameter variation in vibro-impact oscillators, random excitation of vibro-impact systems, vibro-impact dampers, oscillators with a bouncing ball, limiting phase trajectory corresponding to energy exchange between the oscillator and external source, frequency-energy distribution in oscillators with impacts, and discontinuity mapping. The third group is covered in four papers and addresses some industrial applications such as hand-held percussion machines, rub-impact dynamics of rotating machinery, impact fatigue in joint structures.
