Sažetak
In this work, we investigate the influence of the width of a DCB specimen on the fracture resistance. During the experiment, load-line displacement, applied force and crack length are measured continuously. Using the optical measurement system GOM ARAMIS, complete displacement field is recorded during the experiment, which can be used to obtain the actual load-line displacement of the plates and the position of the crack tip. Experimental data is used to compute the fracture resistance of the tested adhesive using methods from standards and novel methods proposed by the authors. In the numerical model we use the beam and plate finite elements and model the adhesive using a bi-linear CZM at the interface.
