Abstract

In this research, it is studied the damage produced on specimens with different geometries. To develop the investigation the non contact optic technique Digital Image Correlation (DIC) is used to measure the out of plane displacements of the defect. The information provided by DIC is post processed with an algorithm designed to quantify geometrical aspects, for example, the area, the volume or the maximum depth of the damage. The results are compared with other obtain with traditional experimental techniques as a dial indicator and a profile projector. Finally damage with irregular geometries, difficult to measure with traditional techniques, are measured with the experimental methodology proposed, highlighting the potential of DIC to analyze external structural damage.
