Description

The program to be described here was initiated during the past year at the Air Force Materials Laboratory. The problem of deterMining adhesive bond strength was undertaken with a rather bruteforce approach of simply collecting the best possible data, utilizing existing ultrasonic plane-wave theory for layed structures to calculate ultrasonic spectra, and then attempting the inversion of the d~ta to obtain the acoustic properties of the materlal or structure. An empirical correlation of these acoustic properties with the destructively measured bond strength is planned.
