Abstract

The fracture energy of brittle materials can be defined as the energy absorbed during the extension of a crack over a unit area of surface formed during the fracture process1. Measurements of fracture energy for polycrystalline ceramic materials have resulted in a wide range of reported values for the same material. This is due to some extent to the method used for measurement1–3, however, more important is the strong dependence of fracture energy on such microstructural variations as grain size4–9 and porosity2,6.
