The author's approach is one of continuum models of the aerodynamic flow interacting with a
flexible structure whose behavior is governed by partial differential equations. Both linear
and nonlinear models are considered although much of the book is concerned with the former
while keeping the latter clearly in view. A complete chapter is also devoted to nonlinear
theory. The author has provided new insights into the classical inviscid aerodynamics and
raises novel and interesting questions on fundamental issues that have too often been neglected
or forgotten in the development of the early history of the subject. The author contrasts his
approach with discrete models for the unsteady aerodynamic flow and the finite element model
for the structure. Much of the aeroelasticity has been developed with applications formerly in
mind because of its enormous consequences for the safety of aircraft. Aeroelastic instabilities
such as divergence and flutter and aeroelastic responses to gusts can pose a significant hazard
to the aircraft and impact its performance. Yet it is now recognized that there are many other
physical phenomena that have similar characteristics ranging from flows around flexible tall
buildings and long span bridges alternate energy sources such as electric power generation by
smart structures to flows internal to the human body. From the foreword: For the theorist and
applied mathematician who wishes an introduction to this fascinating subject as well as for the
experienced aeroelastician who is open to new challenges and a fresh viewpoint this book and
its author have much to offer the reader. Earl Dowell Duke University USA
