The Choice of Spacing in Measuring Displacements for the Evaluation of Strains by the Method of Optical-Digital Image Correlation

We analyze the influence of the size of spacing for measuring the displacements of the surface points on the corresponding macrostrains. We propose an algorithm for the determination of this size in inhomogeneous strain fields. For a specimen of 20 steel stretched by a specified force, we determine...

Zusammenfassung:	We analyze the influence of the size of spacing for measuring the displacements of the surface points on the corresponding macrostrains. We propose an algorithm for the determination of this size in inhomogeneous strain fields. For a specimen of 20 steel stretched by a specified force, we determine the optimal size of spacing, its relationship with the size of structural elements, and correlation with the known characteristics of the material.
