Introduction to Rheology,efined, and their use to describe material behavior is described. Rheological phenomena and the properties used to describe them are presented, including elasticity, viscous flow, viscoelasticity and plasticity. Finally the molecular structures that give rise to the complexity of melt rheology are discussed.

Nonlinear Viscoelasticity: Models,apters, and it will be of interest primarily to those involved in the modeling of melt flow processes in which viscoelasticity plays an important role, such as blow molding and film blowing. Tensor representations of stress and strain are introduced and used to present several models of nonlinear behavior.

Nonlinear Viscoelasticity: Phenomena,o a shearing deformation no longer provides a complete description of rheological behavior. The molecular processes that give rise to nonlinear viscoelasticity are described as well as several large and rapid deformations that used to obtain information about nonlinear behavior. These include large-amplitude oscillatory shear and extensional flow.

Role of Rheology in Melt Processing,ning operations dealt with are those in which elasticity is important. Processes for making sheet and film are described and processing problems related to rheology are explained. The roles of rheology in blow molding, injection molding, rotational molding and foam formation are taken up in the remainder of the chapter.
