Testing the methodology at Empa
The Airbus panel was brought to a convenient size of about 1 m2 by waterjet cutting. The ends were potted to allow force introduction through the platen of the testing machine. The geometry of the panel was controlled in order to update the numerical model for simulation. Finally, a self-adhesive speckle pattern was glued onto the outside of the test panel for DIC deformation measurements.
