Identification of subsurface delaminations in composite laminates
TL;DR: In this article, the authors presented a novel procedure for the identification of delaminations in composite laminated panels from surface displacement measurements, where the damage identification procedure is formulated as an inverse problem where experimental data from digital speckle pattern interferometry (DSPI) out-of-plane displacement measurements are used to quantify the planar location, size, orientation and depth of the flaw.
