Rheology, defined as the science of deformation and flow is now recognized as an important field of scientific study. A knowledge of the subject is essential for scientists employed in many industries, including those involving plastics, paints, printing inks, detergents, oils, etc.
Rheology is also a respectable scientific discipline in its own right and may be studied by academics for their own esoteric reasons, with no major industrial motivation or input whatsoever.
The growing awareness of the importance of rheology has spawned a plethora of books on the subject, many of them of the highest class. It is therefore necessary at the outset to justify the need for yet another book.
Rheology is by common consent a difficult subject, and some of the necessary theoretical components are often viewed as being of prohibitive complexity by scientists without a strong mathematical background. There are also the difficuities inherent in any multidisciplinary science, like rheology, for those with a specific training e.g. in chemistry.
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 on account of their depth of detail and highly mathematical nature.
