Paper Abstract

Moiré interferometric techniques were adapted to facilitate studies on 25.4 mm (1 in.) diameter holes. A replication scheme was developed to produce a high-frequency diffraction grating on the cylindrical surface of a hole. Techniques were developed to interrogate the specimen grating to obtain the in-plane deformations on the hole surface.

The application of the technique to the measurement of interlaminar deformations on the cylindrical surface of a hole in a laminated composite plate is presented. The techniques can be generalized for investigations on both convex and concave singly-curved surfaces.
