Two-dimensional deformation and motion measurements were the foundation of the early applications in digital image correlation for solid mechanics measurements. In all cases, a nominally flat specimen (with or without a geometric discontinuity) was imaged while being subjected to nominally tensile loading. Throughout the loading process, it was assumed that the specimen deformed within the original planar specimen surface.
