Abstract

Rheological (shear) and bulk specimen (tensile) tests for determining creep and stress relaxation properties of flexible adhesives have been compared. The rheological creep property measurements were of poor quality. This may have been due to incremental slippage or de-bonding of the adhesive. The rheological creep measurements showed little agreement with the bulk specimen creep measurements. Consequently, the rheological creep measurements appear unreliable. The stress relaxation measurements were more reliable. The rheological and bulk specimen relaxation measurements were comparable.
