The Laplace transform method of viscoelastic stress analysis is reviewed and applied to the sandwich seal and bead seal. The concept of thermorheological simplicity, the viscoelastic‐elastic analogy, and the role of dilatational relaxation in uniaxial, biaxial, and triaxial stress are discussed. Methods of incorporating measured stress relaxation data into the analysis to provide a realistic description of glass behavior are detailed and closed‐form solutions are derived for the stresses in seals.
