Fracture toughness measurements of LPS-SiC: a comparison of the indentation technique and the SEVNB method

Many methods are currently used to measure the fracture toughness of ceramic materials. Methods based on crack-length measurements of cracks introduced into the sample surface by the Vicker's indentor have the advantage that they are easy to use, but are very unreliable due to subcritical crack...
