Compressive Strength Following Delamination Induced Interaction of Panel and Sublaminate Buckling

A number of panels have been artificially delaminated to produce a range of thin anisotropic sub-laminates. Panels were subject to experimental compression testing in which sublaminate and global panel buckling modes were allowed to interact. A comparison of experimental results with previous results where panel buckling was restrained, demonstrates that interaction of buckling modes causes significant reductions in both panel buckling and...
