Aeroelasticity is the study of flexible structures situated in a flowing fluid. Its modern origins are in the field of aerospace engineering, but it has now expanded to include phenomena arising in other fields such as bioengineering, civil engineering, mechanical engineering and nuclear engineering. The present volume is a teaching text for a first, and possibly second, course in aeroelasticity. It should also be useful as a reference source on the fundamentals of the subject for practitioners. In this third edition, several chapters have been revised and three new chapters added. The latter include a brief introduction to experimental aeroelasticity an overview of a frontier of research nonlinear aeroelasticity and an account of aeroelastic control. The authors are drawn from a range of fields including aerospace engineering, civil engineering, mechanical engineering, rotorcraft and turbomachinery. Each author is a leading expert in the subject of his chapter and has many years of experience in consulting, research and teaching.

'... the text succeeds on three levels: as an introductory text for newcomers to aeroelasticity, as a reference text for professionals working in the field, and as a source book for researchers. The wide range of topics covered provides a fascinating insight into the cross-fertilization that can occur between seemingly disparate engineering disciplines ... There is little doubt that most workers in the field will wish to have access to this text.' Journal of Sound and Vibration, 196:5 (1996)
