Rheology Fundamentals

Most technological improvements are realized through application of rheology used to modify properties of materials. At the same time, rheology is a complex discipline not fully understood by most researchers and engineers. It is not because rheology is too difficult to understand but mostly because the discipline uses its own language full of terms and models, understood by rheologists but not commonly used by others. ChemTec Publishing introduces a new series entitled Fundamental Topics in Rheology, designed to facilitate conversion of rheology from a field familiar to a narrow group of specialists to a popularly applied science.

Experts in rheology and polymer processing present up-to-date, fundamental and applied information on the rheological properties of polymers, in particular those relevant to processing, contributing to the physical understanding and the mathematical modelling of polymer processing sequences. Basic concepts of non-Newtonian fluid mechanics, micro-rheological modelling and constitutive modelling are reviewed, and rheological measurements are described. Topics with practical relevance are debated, such as linear viscoelasticity, converging and diverging flows, and the rheology of multiphase systems. Approximation methods are discussed for the computer modelling of polymer melt flow. Subsequently, polymer processing technologies are studied from both simulation and engineering perspectives. Mixing, crystallization and reactive processing aspects are also included. Audience: An integrated and complete view of polymer processing and rheology, important to institutions and individuals engaged in the characterisation, testing, compounding, modification and processing of polymeric materials. Can also support academic polymer processing engineering programs.

Rheological Fundamentals of Soil Mechanics

Rheology unites the seemingly unrelated fields of plasticity and non-Newtonian fluids by recognizing that both these types of materials are unable to support a shear stress in static equilibrium. In this sense, a plastic solid is a fluid. Granular rheology refers to the continuum mechanical description of granular materials. In this book, rheology--the study of the deformation and flow of matter--is treated primarily in the context of the stresses generated during the flow of complex materials such as polymers, colloids, foams, and gels. A rapidly growing and industrially important field, it plays a significant role in polymer processing, food processing, coating and printing, and many other manufacturing processes.

Rheology: Concepts, Methods, and Applications, Fourth Edition provides a thorough historical and theoretical grounding in the field and introduces rheology as the method for solving many practical problems in materials science and engineering. This new edition has been updated to include new evidence-based methods and applications, coverage of non-Newtonian properties and their effect on material processing, heterogeneity in flow, rheology of highly concentrated emulsions and suspensions, viscosity and viscoelastic behavior of nanocomposites, the behavior of supramolecular solutions, rheology of gels, deformation-induced anisotropy, conformation changes during flow and molecular orientation. The book is practical and relevant for industry, but also consistent with rheology courses in academia, making it relevant to both academics and accomplished rheologists in industry. Includes updates on non-Newtonian properties and their effect on material processing, heterogeneity in flow, rheology of concentrated emulsions, suspensions, and more Discusses viscosity and viscoelastic behavior of nanocomposites, the behavior of supramolecular solutions, rheology of gels, deformation-induced anisotropy, conformation changes during flow, and molecular orientation Covers theory backed by practical examples, methods of measurement and raw data treatment, and various applications

This text introduces the subject of rheology in terms understandable to non-experts and describes the application of rheological principles to many industrial products and processes.

In this book, the necessary background for understanding viscoelasticity is covered; both the continuum and microstructure approaches to modelling viscoelastic materials are discussed, since neither approach alone is sufficient.
