Analysis of standard fracture toughness test based on digital image correlation data

Original language description

This paper deals with an experimental methodology based on the 2D Digital Image Correlation method for precise full-field in-plane stress-strain analysis of a region containing a crack. The presented methodology is employed as a supporting and comparative method for the standard J-integral testing defined by the ASTM. The methodology utilizing the DIC-based displacements for a subsequent evaluation of strain, stress and final extraction of the J-integral from its definition. This J-integral is compared with the value obtained by the ASTM standard and with the value obtained by the DIC-based CTOD measurement. Several techniques improving the conventional DIC and data post-processing are proposed to achieve reliable full-field strain/stress results. A direct comparison between the experimental and FEM full-field results is carried out.
