Interdisciplinary Program for Quantitative Flaw Definition.
Abstract
Document describes three projects as part of the Interdisciplinary Program for Quantitive Flow Definition. Project I is a continuation of the previous effort that led to the establishment of a quantitative capability for measuring the size, shape and orientation of ellipsoidal flaws. Project II is a newly initiated effort with the objective is quantitatively measuring the fracture related properties of surface flaws. Two forms fo interrogating energy are being utilized. Unit A of Project III addresses the long standing problem of predicting the strength of a completed adhesive bond from nondestructive measurements on the joint. Unit B has concentrated on the development of advanced NDE techniques applicable to the graphite epoxy class of fiber reinforced composite materials. Unit C was initited following encouraging nondestructive defect detectability studies in structural ceramics, using high frequency ultrasonics and microfocus X-rays (as well as promising results obtained using microwave methods and acoustic microscopy).
