Opis

In an earlier book, Rheological Measurement (A. A. Collyer & D. W. Clegg, Elsevier Applied Science, 1988), the basic rheological methods of measurement presently used were discussed in the light of the basic underlying principles and current theories. The same approach is adopted in this companion book, which is concerned with some newer or more sophisticated techniques that have resulted from a fresh understanding of the subject, or as a result of improvement in computer control, data acquisition and computational power, or more simply from an industrial need, particularly with regard to process control. The first two chapters deal with the extensional flow properties of fluids and their measurement. This inclusion is in response to a greater awareness in industry of the importance of these flows. Chapter 3 intro duces and develops the subject of surface rheology and the measurement of its properties, again a subject of increasing significance. The methods of measurement of the dynamic mechanical properties of fluids and the calculation of the resulting rheological parameters are discussed in Chap ters 4-7 inclusive. The subject areas covered are: large-amplitude oscilla tory shear, a model for viscoelastic fluids and solids, a new method of measuring dynamic mechanical properties, particularly for curing sys tems, and the use of complex waveforms in dynamic mechanical analysis."

Recenzje

...very readable and will leave the reader wanting to know more. It is certainly a worthwhile buy at L65 - Reactive Polymers; The book will be a useful addition to the rheology bookshelf - Polymer International; ...a valuable source of information... - Acta Polymerica; ...an everyday handbook that will sit in the laboratory by our instruments...it will be a long time before it is superseded because of the unusual combination of techniques covered. - Trends in Polymer Science.
