Abstract
The energy absorption behaviour of composite stiffeners subjected to axial compression has been investigated. A semi-empirical analysis methodology has been developed for prediction of the energy absorption capability of composite stiffeners based on crush tests of flat plate specimens and an understanding of the fundamentals of the energy absorption process. Flat plate, angle and channel specimens were fabricated from T650-35/F584 graphite/epoxy plain-weave fabric using five different lay-ups that consisted of varying percentages of 45° and 0° plies. The specimens were crush tested under axial compression, and measured levels of sustained crushing stress were compared with model predictions.
