N2 - Within this contribution an approach for the simulation of stringer-stiffened composite panels based on the finite element method is developed. Layered shear-elastic shell elements allowing for an arbitrary stacking sequence and a variable location of the reference plane along the thickness are used to model the pre- and postbuckling response of the composite. A ply discount model with constant knock-down factors is employed to account for ply failure which can occur as fiber fracture, matrix cracking, or fiber-matrix shear failure. Delamination, and particularly debonding of the stiffener from the skin, is modeled via interface elements in which the cohesive zone approach is implemented. Numerical validation examples with experimental evidence highlight the performance and applicability of the proposed model.
