Pisarenko Institute for Problems of Strength, National Academy of Sciences of Ukraine, Timiryazevskaya ul. 2, 01014, Kiev, Ukraine aut Fracture toughness testing of materials by the EF method [Elektronische Daten] [G. Gogotsi] Experimental evidence is presented that fracture toughness testing of ceramics by the EF method (fracture of the edge of a rectangular specimen as a result of indentation), which does not rely on modern fracture mechanics concepts, in contrast to its conventional analogs, is easy to implement and can be used under standard laboratory conditions. Testing results for yttria, alumina, zirconia, and silicon nitride ceramics confirm that this method is suitable for practical application. The EF method is well suited for testing nanostructured, dental, and other ceramics, as well as semiconductors, and is capable of providing reliable fracture toughness data even if the amount of material for testing is limited.
