A parametric study of DIC measurement uncertainties of cracked metals
Research output: Contribution to journal › Article › peer-review
Displacements and strains in the presence of a crack in welded steels have been studied using digital image correlation (DIC) under zero load and selected loading conditions. A parametric study has been carried out to assess the effects of some of the key parameters, including subset size, step size, and the size of the measurement window, on the measurement uncertainties for systematic and random errors. The assessments were carried out a region around the crack tip, where high strain gradients and inhomogeneous deformation present significant challenges for DIC measurements.
