The handbook begins with a short introduction (chapter 1) to the viscosity of everyday liquids, and shows the way in which rheology interacts with in-use situations which most of us come across in everyday life at home and work. Then a few chapters follow on the explanation of the different kinds deformation (chapter 2); the use of graphs in general (chapter 3), and rheology graphs in particular (chapter 4). A consideration of the simplest kind of liquid that we will meet comes next the Newtonian liquid (chapter 5), and we then show how we can calculate its flow behaviour in lots of simple geometries (chapter 6). Two chapters cover rheology measurement (chapters 7 & 8), thus equipping us for non-Newtonian behaviour in liquids. A discussion of such liquidswhere the viscosity varies with shear rate (or shear stress)then follows (chapters 9 & 10), with a special section devoted to very shear-thinning liquids that appear to have a yield stress (chapter 11). To complete this part, we discuss the flow, i.e. creep, of solids (chapter 12) under long-term stress. Viscoelastic behaviour is then covered (chapters 13 and 14), first linear viscoelasticity with its manifestations in the time and frequency domain . Then nonlinear displays of viscoelasticity are introduced, these effects being usually encountered in steady-state flow, where overt normal-force effects such as the Weissenberg rod climbing and the extrudate-swell phenomena are seen. The origins of viscous and viscoelastic behaviour are then investigated for suspensions (chapter 15) and polymer systems (chapter 16), showing the important effects of colloidal interactions. Extensional (or stretching) flow results in a very different interaction between microstructural elements such as rods and coils and the surrounding stretching flow field, and this results in very divergent behaviour compared to shear flow (chapter 17). Two applied areas are then covered, first the rle of rheology in the surfactant systems (chapter 18) found in so many everyday products, and then we give a short overview of the rheology of food systems (chapter 19). For those interested in buying journals or books on the subject of rheology, an extensive list is given (chapter 20). The last chapter (chapter 21) considers the growing importance of computing in rheology, where one can now predict the flow of viscoelastic liquids in complex geometries. The book concludes with an Appendix which covers the area of on-line or process viscometry, which although not of great interest to all readers, is nevertheless very important to some.
