Failure Prediction Technique for Compression Loaded Carbon Fibre-Epoxy Laminate with Open Holes:
TL;DR: In this article, the inplane compressive fracture behavior of a carbon fiber-epoxy laminate containing a single hole is examined. Failure is due to 0° fibre microbuckling surrounded by delamination.

Compressive failure of notched carbon fibre composites
TL;DR: In this article, the compressive fracture properties of carbon fiber/epoxy laminates were investigated in terms of existing theories of strength, and it was found that compressive failure is governed by plastic microbuckling of the 0° plies.

Intralaminar fracture toughness of a cross-ply laminate and its constituent sub-laminates
TL;DR: In this paper, the intralaminar mode I fracture toughness values for a M55J/M18 carbon/epoxy cross-ply laminate [0°/90°]15 (alternate 0 and 90° layers) and its constituent sub-laminates are theoretically evaluated on the basis of a modified crackclosure integral (MCCI) method corresponding to the fracture loads obtained by testing C(T) specimens.
