u9 b+ R3 U3 A J. n4 AIn an earlier book—An Introduction to Rheology—we stated that rheology is a difficult subject. However, even though we then tried to make it as simple as possible, a number of people still told us that they found the book hard going. This present book is meant to satisfy this group. For this reason, the mathematical content has been kept to a minimum, and the text is as descriptive as possible: there are no integrals and only the occasional differentiation symbol, with all the equations in the simple algebraic form of A = B.# V: [% n% J/ x0 v7 R: e
The book is suitable as a first introduction to the subject of Rheology for any student of science or engineering. However, having worked in industry for thirty years, I am also trying to meet the needs of my industrial colleagues who—often without any previous training in the subject of rheology—find themselves having to work on the formulation and: U6 F* ]5 e* D" U
processing of non-Newtonian liquids. The contents of this book are expansions of lectures that I have given to both these groups of people over the years, in introductory rheology courses run by rheometer companies, training organisations and universities around the world.
/ k" ?! d5 p1 IBefore leaving this foreword I must mention two rheologists and two rheology books. Dr. George Scott Blair, the ‘grand old man’ of British Rheology, was the first author to produce a book called Elementary Rheology (Academic Press, London, 1969), written as he said, on Rheology, but ‘not intended for rheologists’! The present author worked in his0 K2 m* `" ?; u6 X
laboratory for a few months during a summer vacation as an undergraduate in the early 1960’s. His parting words on that occasion were ‘I hope you catch the Rheology bug’. The bug was truly caught, and this book is intended to spread the infection even further!
; `) S5 X! j) X2 q MThen, An Introduction to Rheology for me marks my gratitude to Prof. Ken Walters FRS, one of my co-authors of that book. He introduced me to the world of theoretical rheology as a postgraduate student at the University of Wales, Aberystwyth and thereby gave me of a wide appreciation of most aspects of rheology. Over 5000 copies of An Introduction ... have now been sold and this present book has been written, in effect, as an9 E6 e3 E1 {" x' m
