Description
New nondestructive techniques are being sought to detect and characterize defects in aging aircraft structures. One problem of particular concern is the inspection of bonded and riveted lap joints between aluminum alloy sheets comprising the aircraft’s external skin. Over time, mechanical stresses, thermal stresses, and corrosion lead to disbonds in these regions which degrade the integrity of the joints. A rapid and economical nondestructive evaluation technique is desired to detect and quantify the severity of these disbonds, including the so called “kissing” disbonds where there is no material missing in the adhesive layer and all layers are in physical contact.
