Abstract

Basic fundamentals of the elastic behavior of a standard linear solid and the internal friction technique based on this model are briefly described. The internal friction (Q-1) caused by various thermally activated processes in vitreous solids are reviewed for several glass compositions in relation to atomic mobility and other relevant properties. A similar relaxation mechanism is the inherent feature of different vitreous solids. The present authors suggest that the mechanisms responsible for the internal friction peaks in selenium-based glasses are closely related to the polymeric structure. These peaks exist in many polymers and may be considered as they universal feature..
