To design aeronautical composite multi-stringer panels that can safely operate in a postbuckled state, it is important to identify the parameters that can influence the different modes in which skin-stringer separation might occur. A methodology is under development to study the interaction between the skin-stringer separation and the postbuckling deformation. A simple criterion that can predict the initiation of skin-stringer separation is developed using the building block approach and single-stringer specimens. The criterion identifies whetherthe initiation is mainly due to bending or twisting deformations, so that these two possible modes can be studied separately. This procedure has the potential to reduce the overall development cost and allows the investigation of the design parameters that might precipitate or delay the skin-stringer separation.
