I, Bob Clemintime, based many of the diagrams in this drawing on diagrams done by Brian Lawn in his book "Fracture of Brittle Solids"(Lawn, B. (1993). Microstructure and toughness. In Fracture of Brittle Solids (Cambridge Solid State Science Series, pp. 194-248). Cambridge: Cambridge University Press. doi:10.1017/CBO9780511623127.009). He graciously provided his permission for his drawings to be used as a derivative work and published on Wikipedia.
