Experimental and numerical investigations of compression stability of stiffened composite panel with ply interleaving

A novel composite layup technique (ply interleaving) is proposed to satisfy the extraordinary needs in aircraft structure design. Buckling experiments and corresponding simulations with different configurations are carried out to study the mechanical properties of the stiffened panel with this ply layout and get a suitable numerical prediction method. A ply-by-ply-based modeling technique is applied to characterize the real discontinuity in each...
