Abstract The residual strength in FMLs can be described differently depending on the geometry of the initial damage. Theories and prediction models are presented for through-cut cracks and fatigue through cracks, based on R-curve and critical crack tip opening angle concepts. For part-through cracks, linear relations based on a damage ratio are presented, while for surface cracks a method is presented based on the through-thickness strain distribution, in combination with the corresponding stress concentration factor. In the end the damage tolerance after impact is discussed, explaining how the residual stress state in the plastically deformed dent improves the residual strength.
