Abstract
The digital image correlation (DIC) method is an advanced technical method to measure material strain by comparing several captured figures during deformation. DIC provides full-field displacements and full-field strains in recorded images. In fact, there is much software using the DIC algorithm. However, a commercial DIC system requires a high initial investment. In this study, the DIC algorithm was built based on the open-source of Matlab software, temporarily called NCORR DIC . A DIC system was built including a computer system, extensometer, tensile testing machine, high-resolution camera, NCORR DIC software and applied for AL5052 sheet metal test sample. After obtaining the images from the tensile test , the entire image will be included in the NCORR DIC software for processing. To check the accuracy of the DIC system, the results of the stress-strain curve of NCORR software were compared with the standard test method using extensometer. The obtained results measured from NCORR DIC software were imported into a finite element method (FEM) software to check the accuracy of this method. Moreover, the hardening model (Voce, Swift, Kim-Tuan) provides empirical evidence and prerequisite conditions for the development of new fracture criteria to describe behavior fractures .
