Although the use of fibre-reinforced composites has spread increasingly in the design of primary structures, the prediction of the behaviour and damage until the final failure of structure subjected to complex multiaxial loadings still remains a major problem in the design of composite parts. An advanced damage and failure approach, which permits to predict accurately the damage and failure of composite structures subjected to complex multiaxial 3D loadings, has been proposed. This approach has been compared successfully with test results on laminates subjected to multiaxial loadings extracted from the literature or performed at Onera. Moreover, finite element simulations on different structures subjected to complex loadings have also been performed to determine the predictive capabilities of such an approach.
