Abstract

This Letter presents the results of a study of the radial displacement fields arising upon stretching of cylindrical samples before their disintegration. The object of study was sv-07Kh16N6 stainless steel wire containing filiform defects oriented along the sample axis. Using X-ray tomography of the sample necks, the coordinates of the defect points in the sample are determined and the displacement field is recovered from them. The resulting dependence is represented by an approximate formula.
