This volume contains selected papers presented at the Symposium on "Recent Developments in Non-linear Oscillations of Mechanical Systems", held in Hanoi, Vietnam, from 2 - 5 March 1999. This Symposium was initiated and sponsored by the International Union of Theoretical and Applied Mechanics (lUI AM) and organised in conjunction with Vietnam National University, Hanoi. Ihe purpose of the Symposium was to bring together scientists active in different fields of oscillations with the aim to review the recent progress in theory of oscillations and engineering applications and to outline the prospects in its further achievements to then co-ordinate and direct research in this field to further co-operation between scientists and various scientific institutions. An International Scientific Committee was appointed by the Bureau of IUI AM with the following members: Nguyen Van Dao (Vietnam, Co-Chairman) E.J. Kreuzer (Germany, Co-Chairman) D.H. van Campen (The Netherlands) F.L. Chernousko (Russia) A.H. Nayfeh (U.S.A) Nguyen Xuan Hung (Vietnam) W.O. Schiehlen (Germany) J.M.T. Thompson (U.K) Y. Veda (Japan). This Committee selected the participants to be invited and the papers to be presented at the Symposium. As a result of this procedure, 52 active scientists from 16 countries responded to the invitation, and 42 papers were presented in lecture and poster discussion sessions.

Klappentext

This book contains 32 selected papers by acknowledged experts covering current research in this field of mechanics. The material has been grouped into six sections entitled: Non-linear oscillations of beams, plates, vehicles, and other dynamic systems; Analysis and control of non-linear systems; Non-linear waves; Dynamics of offshore structures; System identification; and Mathematical and numerical methods for investigating non-linear systems. Individual papers reflect the newest achievements and results in non-linear oscillations and cover analytical methods, experimental and/or numerical techniques which may be applied to dynamic problems. This volume will be of interest to scientists and graduate students in theoretical and applied mechanics and mathematics.
