A combined mesh and model adaptive strategy for the scaling issues in the numerical modelling of the ductile damage in thin panels Original Research Article

In this paper, a combined model and mesh adaptive computational approach is presented for the numerical modelling of ductile damage in thin panels. The aim of such a strategy is to be able to compute with the finite element techniques, the damage tolerance of large structures, such as a fuselage, in a fully coupled way, taking into account the multiscale character of the problem. In a sole computation, both global structural features at the macroscale level––such as fasteners, stiffeners and joint configuration––and a realistic material damage behaviour at the microscale level are treated in a coherent way.
