Abstract
The present work shows the practical application of digital image correlation (DIC) technique for fracture toughness (KIC) 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 (KIC) value is validated by comparison with fracture toughness (KIC) 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.
