Description

The performance of adhesive bonds in primary structures strongly depends on the quality of adhesion. Many NDE methods are presently used to detect unbonded areas; however, these methods cannot be used to determine bond properties. In standard ultrasonic techniques, the velocity of bulk wave propagation through the specimen is measured by time-offlight. Unfortunately, the waves reflected from the bonded region cannot be easily identified or analyzed to determine the properties of the adhesive layer.
