This report contains a review of the technical literature concerning the detection, location,
and characterization of structural damage via techniques that examine changes in measured …

A powerful new method for residual stress measurement is presented. A part is cut in two,
and the contour, or profile, of the resulting new surface is measured to determine the …

For most of the destructive methods used for measuring residual stresses, the relationship
between the measured deformations and the residual stresses are in the form of an integral …

This article reviews the technical literature on the determination of a residual stress profile
by successive extension of a slot and measurement of the resulting strains or displacements. …

This paper provides an overview of methods to detect, locate, and characterize damage in
structural and mechanical systems by examining changes in measured vibration response. …

Through-thickness residual-stress profiles in rolled 7050-T74 aluminum plate were measured
before and after stress relief by stretching (-Tx51). Measurement required adapting the …

Plates (25.4mm thick) of aluminum alloys 7050-T7451 and 2024-T351 were joined in a butt
joint by friction stir welding (FSW). A 54mm long test specimen was removed from the parent …

We describe non-contact scanning with a confocal laser probe to measure surface contours
for application to residual stress measurement. (In the recently introduced contour method, a …

The conventional contour method determines one component of residual stress over the cross
section of a part. The part is cut into two, the contour (topographic shape) of the exposed …

… The authors would like to thank their longtime collaborator Michael R. Hill of the University
of Califonia, Davis, who has been as instrumental in the development of the contour method …
