We investigate by numerical simulation the system size dependence of theshear delamination strength of thin elastic films. The films are connected to arigid substrate by a disordered interface containing a pre-existing crack. Thesize dependence of the strength of this system is found to depend crucially onthe crack shape. For circular cracks, we observe a crossover between asize-independent regime at large crack radii which is controlled by propagationof the pre-existing crack, and a size-dependent regime at small radii which isdominated by nucleation of new cracks in other locations. For cracks of finitewidth that span the system transversally, we observe for all values of thecrack length a logarithmic system size dependence of the failure stress. Theresults are interpreted in terms of extreme value statistics.
