In the case of relatively brittle structural materials, linear fracture mechanics provides an analysis basis for testing and control of fracture strength. Standardized methods of crack toughness testing are available only for metals which can be pre-cracked by fatigue. Hence, further work on this t

The first ply failure in composite laminates are studied by 3-D fracture mechanic approach. The fracture model is based on a crack embedded in one of the inner layers. Numeriil results for the case of "angle ply" laminates are based on a general 3-D finite difference progtam. Stress intensi~ factor
The authors feel that the sample geometry and notch depth selected were adequate for the experimental purposes, The sample geometry is consistent with that of other work on ceramic materials, glasses, graphites, and rigid polymers (2,3,4) and is consistent with the analysis of Gross and Srawley (5).
