A Criterion for Mixed-Mode Matrix Cracking in Graphite-Epoxy Composites

Source

In this paper, mixed-mode matrix fracture in graphite-epoxy composites was studied. Experimental investigation was conducted on a family of doubly side-notched unidirectional off-axis specimens. By varying the notch depth and the off-axis angle, a total of 28 fracture conditions of differing mixed-mode ratios were produced. Fracture analysis of the test data suggested that the total strain energy release rate is a suitable material condition for mixed-mode matrix cracking in graphite-epoxy composites.
