A novel two-way global-local coupling approach to model progressive separation of skin and stringer in combination with intralaminar damage in stiffened CFRP panels under compression is presented. The methodology makes it possible to examine the damage at two levels of accuracy, taking advantage of fast calculations at the global level and assessing in detail the damage propagation at the local level. The required appropriate information exchange between the global and local level in both directions has been attained. This chapter presents an overview of this efficient approach for progressive failure analysis of composite panels and illustrates the approach on the basis of a one-stringer panel, in particular for the case of skin-stringer debonding.
