Although numerical models are gradually improving, a relevant description of local phenomena such as fracture or crack propagation is still out of reach. As a result, the scope of these models is often restricted as far as the question of reliable prediction is addressed. This is the case even if the quantity of interest to be evaluated does not lie in the vicinity of the local phenomenon. As a possible solution to this issue, we propose here to use the Arlequin framework [BEN98, BEN05] to mix

Let us recall here that the Arlequin method is a versatile numerical approach which, as shown in Figure 1 , allows for the superposition and coupling of different models on a specific zone, typically a surface or a volume.
