Integración de Proyección de Franjas y Correlación digital de imagines 2D para la medida de deformaciones y desplazamientos

Abstract

This thesis presents a novel system to measure displacements in X-, Y-and Z-directions occurring on the surface of an object under deformation. The employed method is based on combining 2D-DIC and FP techniques. This proposed system obtains those results from the acquisition of only one image per each stage of the deformation of the object, enabling real time data acquisition. In addition it allows a complete and simple calibration procedure of the required parameters for the correction of the measured in the plane displacements. To illustrate the potential of the proposed system it has been performed a series of static and dynamic experiments. The results were compared with those obtained using a Digital Mapping 3D images commercial system, showing a high level of concordance with differences lower to 5%.
