Fig. 8.

On the left: side view of post-mortem specimen subjected to peeling test. The specimen’s upper layers are obtained with an increasing nonlocal character ($\delta$), whereas the lower layers behave locally. On the right upper part: force versus displacement plots (normalised with respect to the peak force registered among all the different cases) resulting from the peeling test of thin films with varying nonlocal horizons $\delta$. On the lower right: for various ratios of horizons to thin element height ($\delta /$H), the ratio between the work done to deform the structure at the end of the test and surface free energy ($\mathbb{W}/{\mathcal{G}}_{\mathit{Ic}}$) and the length of the crack to plate height ratio ($d_{\mathit{crack}}/H$), are reported
