Rheology is, by common consent, a difficult subject and some of the theoretical components are often viewed as being of prohibitive complexity by scientists without a strong mathematical background. There are also the difficulties inherent in any multidisciplinary science like rheology for those with a specific training. Therefore, newcomers to the field are sometimes discouraged, and for them the existing texts on the subject - some of which are outstanding - are of limited assistance because of their depth of detail and highly mathematical nature.
This book introduces the subject of rheology in terms understandable to non-experts and describes the application of rheological principles to many industrial products and processes. It provides a simple but authoritative guide which shows clearly how mathematics, physics and chemistry have contributed to the development of rheology. The generic features of all liquid-like materials are summarised, i.e. viscosity, linear viscoelasticity, normal stresses and extensional viscosity. Particular systems are then discussed, i.e. polymeric liquids and suspensions. The final chapter gives an outline of the theoretical advances which have been made. Consistent notation and nomenclature have been used throughout the book, and the key textbooks and publications which will enable the reader to follow up particular topics are listed.

@from:David V. Boger, The University of Melbourne, Australia @qu:Barnes and Hutton, with their years of industrial experience in application of Rheology, have combined with the academic maturity of Walters to create the first text for the beginner in Rheology - either for the student who has not had the appropriate formal training, for the industrial scientist, or for the industrial manager who needs sufficient information to be convinced that knowledge extending beyond a shear rate dependent viscosity may be necessary to solve his or her problem... Overall, the book will be a necessary part of your Rheology library, but most importantly it provides a well written and useful introduction to the subject and thus will be the first book for the newcomer to the subject. @source: @qu:I can thoroughly recommend it to the newcomer to the field and it would provide an excellent introductory text for any course on rheology. @source:Endeavour @qu:...is full of useful tips and references... @source:Polymer International @qu:A highly recommended introduction reflecting the authors long association with the subject of rheology. @source:RACI Polymer Division News
