Description

To determine the presence of delaminations in adhesively bonded layers bv ultrasonic methods, the changes which occur in the propagating ultrasonic energy must be uniquely attributable to the delamination effects. Determination of absolute attenuation and its variation in each adherend layer is prerequisite. In addition, the distinction between adhesively bonded interfaces from those just in physical contact must be established. In this paper, we describe a systematic study of the effect of compression on bonded and unbonded areas on ultrasonic attenuation. The results of the simulation experiment are used to interpret digital images of adhesively bonded polyethylene-rubber-steel piston inserts.

Determination of Delaminations in Adhesively Bonded Layers under Compression
