title: Inplane displacement of a stressed membrane with a hole measured by holographic interferometry.
abstract: The application of holographic interferometry techniques to measure the deformation parallel to the surface of a membrane stressed parallel to its surface is described. The holographic technique used is conventional and is not insensitive to motions orthogonal to the applied stress; however, the object, a rubber membrane, is such that the principal object deformation is in the plane of the membrane and is thus revealed in the holographic image without any data reduction. The holographic results are compared with computed displacement distributions obtained from integrations of classical solutions of the stress equation. The agreement of good the holographic and theoretical stress equation solution is very good.
