Stastical considerations in the analysis of data from fatigue tests on delaminated cross-ply graphite/epoxy composites
Article Abstract:
Results demonstrate that the branching angle follows a normal distribution as a function of number of cycles and the crack growth increases with the magnitude of the branching angle. Data also indicate that crack growth is faster with dissimilar crack failures.

Interlaminar fracture toughness of a graphite/epoxy multidirectional composite
Article Abstract:
Results show that the interlaminar fracture toughness for Omicron/Theta interfaces of multidirectional composite laminates is constant for Theta changes from 15 to 19 degrees and is lowest when Omicron=Theta degrees. Data further indicate that specimen width influences toughness and the crack-length-to-span ratio governs the delamination crack.

Single-edge and double-edge cracks in a fully anisotropic strip
Article Abstract:
Results show that effect of anisotropy on the stress intensity factor depends strongly on the relative crack length being greater. Data on a fully anisotropic strip with a single and double-edge cracks are presented.
