This book is addressed to engineers and other industrialists involved in polymer processing as well as researchers working in the field of rheology and continuum mechanics. Its objective is to foster exchanges between the two groups and hence make a significant contribution to the understanding of polymer processing. The authors first review basic principles of continuum mechanics and heat transfer which are essential for the analysis of the flow of viscous and viscoelastic materials. The modelling of screw extrusion is extensively covered with a multiple faced study of the screw/barrel system. Further on the problem of pressure build-up for molten polymers using the analogous concepts of hydrodynamic lubrication is discussed. Models are developed to simulate the stretching and the biachsial drawing of polymeric liquids and melts. Finally a simple treatment of the basic constitutive equations for visoelastic liquids are presented. This book is at the crossroad of research and industrial practice. Engineers and technicians involved in plastics processing will find here the basic notions of continuum mechanics and heat transfer, and simple methods to solve flow problems associated with polymer processing. Researchers in the field of rheology and continuum mechanics will find in this book an original presentation of constitutive equations, themes for research projects and applications for their theories. Designed as a text for teaching, this book contains numerous problems that require a good grasp of the topics. It is a very useful tool for teachers and students as well as a basic reference for process engineers.
