Abstract

Structural relaxation, which is generally called physical aging by polymer scientists, has been a subject of intense interest for decades to manufacturers of inorganic glasses. Glasses used in optics must be extremely homogeneous, so density fluctuations must be minimized through annnealing; moreover, their brittleness necessitates carful management of stresses. Therefore, the relaxation behavior of inorganic glasses, including the influence of structural relaxation on stress relaxation, has been closely studied, and a very successful phenomenological theory has been developed. This paper briefly reviews the foundation of the theory, and illustrate its application in stress analysis in composites.
