Notes:
This review article, supported by some original experimental results, explains the nature of the Cook-Gordon (C-G) mechanism of crack blunting. Examples are given of how the C-G mechanism influences the toughness of several anisotropic materials: fibrillated polymeric films, composites based on oriented polymers, and beech and spruce woods. Moreover, the C-G mechanism can explain the effects of orientation on anisotropic photo-oxidative degradation of semicrystalline polymers, and also the sudden embrittlement of polymeric films exposed to UV light under stress.
