| Outline of Final Research Achievements |
Probabilistic evaluation of compressive strength of composite stiffened plate is studied by focusing the debonding of the interface between the skin and frange. The failure of the skin/frange interface was discussed fracture mechanically first and the toughness of the skin/frange interface can be used to predict the debonding of skin/frange interface. Then, the interlaminar tensile strength of the laminate was measured and the interfacial strength was probabilistically evaluated. Finally, a finite element analysis was performed for a composite stiffened panel. The failure load and the expected position of failure mechanically assessed agreed well with the experiment done at JAXA before.
