Purpose of the test campaign: the purpose of these experiments was to investigate a new design criterion for mode I characterization of bi-material bonded joints. The bi-material Double Cantilever Beam (DCB) specimens were tested. Test equipment: all tests were performed on a 20 kN tensile test machine. The crack length was measured by means of a Digital Image Correlation (DIC) system or a camera system. The applied force and displacement were measured by the tensile test machine, and also sent as inputs to the Digital Image Correlation (DIC) system or to the camera, in order to facilitate synchronization of the data.
