Preface to Third Edition

The publication of a third edition and its accompanying solutions manual has allowed
me to take a close look at the contents of the book and also to test the accuracy of the
answers to the examples in the text and the problems set at the end of each chapter.
I have reorganized the book into two parts as opposed, previously, to three. Part I,
Elasticity, contains, as before, the first six chapters which are essentially the same except
for the addition of two illustrative examples in Chapter 1 and one in Chapter 4.
Part 11, Chapters 7 to 13, is retitled Aircraft structures, with Chapter 12, Airworthi-
ness, now becoming Chapter 8, Airworthiness and airframe loads, since it is logical
that loads on aircraft produced by different types of manoeuvre are considered
before the stress distributions and displacements caused by these loads are calculated.
Chapter 7 has been updated to include a discussion of the latest materials used in
aircraft construction with an emphasis on the different requirements of civil and
military aircraft.
Chapter 8, as described above, now contains the calculation of airframe loads
produced by different types of manoeuvre and has been extended to consider the
inertia loads caused, for example, by ground manoeuvres such as landing.
Chapter 9 (previously Chapter 8) remains unchanged apart from minor corrections
while Chapter 10 (9) is unchanged except for the inclusion of an example on the
calculation of stresses and displacements in a laminated bar; an extra problem has
been included at the end of the chapter.
Chapter 11 (lo), Structural constraint, is unchanged while in Chapter 12 (1 1) the
discussion of the finite element method has been extended to include the four node
quadrilateral element together with illustrative examples on the calculation of element
stiffnesses; a further problem has been added at the end of the chapter.
Chapter 13, Aeroelasticity, has not been changed from Chapter 13 in the second
edition apart from minor corrections.
I am indebted to, formerly, David Ross and, latterly, Matthew Flynn of Arnold for
their encouragement and support during this project.
