Part of the Progress in Colloid & Polymer Science book series (PROGCOLLOID, volume 80) Papers Table of contents (31 papers) About About these proceedings; Table of contents Viscoelastic relaxation in amorphous bulk polymers. S. Wartewig, I. Alig, F. Stieber, G. Fytas. Book Description Explores the nature of relaxation phenomena in polymers on the basis of time-temperature equivalence. Its role in the physical and mechanical behavior of polymers materials and fundamentals of thermoplastics processing are discussed. This book contains seven chapters that specifically tackle the scientific and engineering aspects of glass viscosity, viscoelasticity, relaxation, and annealing. This book considers first the basis for the analysis of the data produced in relaxation experiments by testing a variety of mechanical models that help to define many of the viscoelastic properties and to establish relationships Book Edition: 1. Viscoelastic Properties of Polymers examines, in detail, the effects of the many variables on which the basic viscoelastic properties depend. These include temperature, pressure, and time; polymer chemical composition, molecular weight and weight distribution, branching and crystallinity; dilution with solvents or plasticizers; and mixture with.
Viscoelasticity: Phenomenological Aspects provides information pertinent to the phenomenological aspects of viscoelasticity. This book provides the basic approach to the behavioral description of viscoelasticity. Organized into seven chapters, this book begins with an overview of the development of various theories of linear viscoelastic Book Edition: 1. About this book A revised molecular approach to a classic on viscoelastic behavior Because viscoelasticity affects the properties, appearance, processing, and performance of polymers such as rubber, plastic, and adhesives, a proper utilization of such polymers requires a clear understanding of viscoelastic behavior. polymers, are time-dependent and perfectly elastic deformation and perfectly viscous flow are idealizations that are approximately reached in some limited conditions. Viscoelasticity is, then, the study of the response of polymers (or other materials) which exhibit some of the features of both elastic and viscous behavior. In chapter 6 we have learned how a deformation of the polymer causes stress in the polymer. We have also learned in chapter 4 that the polymer molecules are mobile: the Kuhn segments of the macromolecule rotate and the entire molecules reptate. Due to this mobility any stress will reduce with time. This is called stress relaxation.
Now in its third edition, Introduction to Polymer Viscoelasticity remains a classic in the literature of molecular viscoelasticity, bridging the gap between primers on polymer science and advanced research-level monographs. Assuming a molecular, rather than a mechanical approach, the text provides a strong grounding in the fundamental concepts, detailed derivations, and particular Cited by: (), a tensile relaxation test was used to characterize the viscoelasticity of an epoxy component by determining the material relaxation modulus as a function of time. Beake () also used nanoindentation to investigate the creep behavior of semi-crystalline and amorphous polymers. Experimental data - for the first twenty seconds of load. Viscoelastic response is often used as a probe in polymer science, since it is sensitive to 1Foranoverviewof nonlinear viscoelastictheory,yetal.,Creep and Relaxation of Nonlinear Viscoelastic Materials, DoverPublications,NewYork, 1. This book also describes the main trends in the investigation of interrelated properties of polymers, such as thermal (heat capacity, thermal conductivity, and thermal expansion), acoustical, dielectric, and viscoelastic, which maintain the physical properties of polymers at low temperatures.
