Methods for measuring the linear viscoelastic properties of thin adhesive layers and for determining the stress intensity factor characterizing the driving force for adhesive failure were developed. A variety of correction factors were introduced that depended on the ratio of the contact radius to the adhesive layer thickness. The large stress intensity factors observed were related to a Dugdale model of the cohesive zone at the contact edge.
