Summary on Grant Application Form |
|
A kissing bond (alternatively called a zero-volume disbond) is a type of disbond in an adhesive joint in which the disbonded surfaces are in some way coupled. As with any disbond they can reduce failure stress, fatigue life, structural stiffness as well as aiding water ingress. Ultrasonics offer a means of detecting such disbonds nondestructively. Previous work as been limited to artificially introduced defects and the relationship between these defects and kissing bonds in real structures is not known. It is the aim of this project to investigate the nature of kissing bonds in real structures subject to real loadings and environmental conditions. This information will enable the most appropriate model of the interaction of ultrasound with a kissing bond to be selected. Possible mechanisms for the creation of kissing bonds in real structure will be studied. Kissing bonds will then be created in the laboratory. Ultrasonic reflection and transmission coefficient measurements (both longitudinal and shear waves) will be used to interrogate the kissing bonds and their detectability will be assessed. These experimental results will be used to verify the selected model.
