✦ Synopsis
Residual stresses in adhesively bonded joints due to shrinkage (chemical reaction) or thermal movement of the adherents are likely to reduce load capacity of an assembly. In this paper rheometric measurements are used to evaluate the change of viscoelastic properties of the adhesive while curing as well as to determine the perpendicular forces developing in the adhesive joint during the curing process. The results give an indication of potential disturbances in the adhesives polymer network due to residual stresses and relaxation in the transition from the liquid to the solid state.
