Summary:The non-destructive digital image correlation (DIC) technique was applied in this study. The goal is to characterize the influence of a stress concentrator through the strain distribution during quasi-static tests. [...]the experimental tests were simulated numerically using the finite element method, showing good agreement between the numerical and experimental results, and thus obtaining information from the innermost layers. Keywords - CFRP, Finite element method; DIC, Damage progression.
