| Description | Journal: Iop Conference Series: Materials Science and Engineering The present work shows the practical application of digital image correlation (DIC) technique for fracture toughness (K$ _{IC}$ ) calculation. DIC is a non-contact, optical technique for measuring full-field displacements and strains by comparing an image of a deformed specimen surface to a reference image taken at un-deformed state. These captured images are correlated and the surface displacements are calculated from which the crack mouth opening displacements (CMOD) is determined. Results of DIC fracture toughness (K$ _{IC}$ ) value is validated by comparison with fracture toughness (K$ _{IC}$ ) value calculated from clip gauge. It is observed that the results obtained by DIC are in close agreement with the results obtained through conventional methods. |
