Introduction to Mechanical Characteristics in Polymeric Solids: Lecture 2 Rheology of Polymer Solids

Abstract

This article explores the phenomenological aspects of the mechanical behavior of polymer solids, particularly focusing on their linear viscoelastic responses in the initial stages of deformation. The standard linear solid model is employed as the primary framework, with serving as a foundational tool to understand rheological responses. The characteristic times, such as relaxation and retardation times, are derived from static and dynamic tests, and their temperature dependence is discussed based on the time-temperature superposition principle. In addition, this article deals with a discussion on dissipation process based on the Eyring theory of thermally activated flow.
