Fig. 7

Illustration of the facet interactions for a growing crack. Small facets formed at an early stage grow independently. At later stages, large facets can align, causing amplification of the stress (panel a). Further facet growth can lead to overlapping configurations, which reduces the stress at the tips due to shielding (panel b).
