Abstract
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 delamination propagation strains. This indicates that the current industry practice of using separate tests to define allowable strains for panel buckling and damage tolerance may be unconservative. A combination of a Shanley model with a computationally efficient analytical Strip model, conservatively predicts values of compressive strain below which propagation of delaminations will not occur.
