Fundamental Aspects of Viscoelastic Response,iscous fluids. Materials that respond in such manner are called viscoelastic, and their mechanical properties have an intrinsic dependence on the time and temperature at which the response is measured. To put this into context, the chapter compares the nature of the response of elastic, viscous, and

Temperature Effects,ple and the concept of time–temperature shifting are introduced first. The dependence of the glass transition temperature both on the time of measurement and on surrounding pressure is examined in detail. The integral and differential constitutive equations are then generalized to include thermal st

The chapter then introduces two types of analytical forms, typically used to describe mechanical constitutive property functions. One type, usually referred to as a Dirichlet-Prony series, is expressed as a finite sum of exponentials; the other form is
