In-Plane Moire Strain Analysis of Bent Plates
A simple experimental method to strain analyze bent plates is described which has advantages in many cases with respect to the conventional determination of slopes using the out-of-plane moire method. The new method consists in determining in-plane displacements using in-plane moire techniques. Strain and stress distributions can be readily obtained from the moire patterns for plates subjected to small as well as large deflections. Two examples of plate bending, one with small deflection and the other with large deflection, are included as illustrations. These are respectively: a simply supported square plate under uniform pressure, and a square cantilever plate subjected to corner load.
