1 July 1988 Composite Grating For Moire Interferometry
Author Affiliations +
This paper presents the theoretical background and experimental verification of a new composite grating with two different grating frequencies, which was developed for simultaneous measurements of small and large displacements in a single specimen using moire interferometry. A composite grating with line frequencies of 1200 and 300 lines/mm was used to study the changes in the displacement field and the approximate J-integral values of a 5152-H32 aluminum, single-edge-notched specimen under increasing load.
