The moire effect or the fringe pattern formed by superimposing two arrays of dark and light line patterns is utilized in experimental mechanics to measure deformations of bodies subjected to external loads. Although mainly a laboratory tool the techniques have been applied to problems in the mechanics of composite materials to map strain concentrations around holes, cracks, and delamination, as well as examining edge effects, shearing deformation, and mechanically fastened composite material.
