Abstract
In this article, we present numerical enhancements of a multiscale domain decomposition strategy based on a LaTIn solver and dedicated to the computation of the debounding in laminates. We show that the classical scale separation is irrelevant in the process zones, which results in a drop in the convergence rate of the strategy. The scalability is restored by performing nonlinear subresolutions in the vincinity of the front of the crack, at each prediction stage of the iterative solver.
