This work focuses on the development of an experimental technique which can help to define the key parameters for post-impact behaviour of laminated composite panels. To address this issue, finite element models were built to represent delaminations based on the observations of CT-scans of impacted samples. The results of these models have been correlated to experimental data obtained using a slope fullfield measurement technique: deflectometry. This work also develops a new damage indicator based on the application of the virtual fields method to compute a local equilibrium gap. The procedure is first presened and then applied to beam and plate samples. The experimental results illustrate the remarkable sensitivity of this measurement meth...
