Abstract
Photogrammetry and image processing have been used extensively to examine surface deformations. Digital Image Correlation (DIC) detects the two-dimensional subpixel displacements between two images in order to analyze deformations in geomechanical structures. In this study, the case of large deformations involving nonlinear elastic behavior of the material has been examined with the use of a physical model of Ethylene Vinyl Acetate (EVA) foam subject to axial strain up to 15%. The associated strain and displacement fields are reconstructed using DIC and compared with the Finite Element Method. DIC is used to analyze the critical hysteresis effect of the material which occurs during loading and unloading process. The results show that DIC is a reliable technique to analyze the nonlinear elastic behavior of materials.
