Environmental and Viscoelastic Effects on Stresses in Adhesive Joints
This paper considers the state of the art in several important areas of research on adhesively bonded joints. The paper reviews the studies dealing with environmental and viscoelastic effects on stresses in adhesive joints. Environmental factors that affect stresses include temperature and moisture. These factors are analyzed and practical examples that illustrate their impact on adhesives are given for the solid-rocket motor, which is a structural component paramount to the U.S. space program. The paper deals with viscoelastic effects on adhesive joints, and a number of viscoelastic models used in the analysis of viscoelastic materials, including adhesives, are reviewed. The use of the solid-rocket motor as an example characterizes the circumstances where viscoelastic properties of adhesive layers are essential. Close attention is paid to the fractional derivative model of Bagley and Torvik, which may be a good candidate for an analytical study of adhesive joints. Finally, existing studies on viscoelastic adhesive joints are considered.
