| dc.description.abstract | The goal of this work is the development of an experimental technique to measure the displacement field and to perform detection of unbonded regions [1] in a single lap joint [2, 3]. The proposed experimental technique is based on the use of Moiré Interferometry. It is a field technique that allows in-plane displacement measurements without contact and with high resolution [4, 5]. Grating replication techniques were developed to record high quality diffraction gratings onto the specimen’s surfaces [6]. It was also, developed an optical assembly of laser interferometry used to generate the master grating (virtual) [7]. A tension load was applied to a lap joint and its deformation was accessed by the interference between the reference grating, recorded on the object surface, and virtual master grating generated by laser interferometry. A phase shifting technique [8] was developed to allow the phase map calculation. Image processing techniques [9] will be used to assess the in-plane displacement field. A finite elements code (ANSYS®) will be used to calculate the displacement field [10, 11]. An unbonded region in a single lap joint was numerically simulated and the obtained results will be compared with those obtained in the experimental work. In the figure 1 it’s possible to observe the displacement field, measured in a horizontal direction, of a single lap sound joint: and the results obtained by numerical simulation. | por |
