Bibliography
ISO 18756:2003 describes a test method that covers the determination of fracture toughness of monolithic ceramic materials at room temperature by the surface crack in flexure (SCF) method.This International Standard is intended for use with monolithic ceramics and whisker- or particulate-reinforced ceramics that are regarded as macroscopically homogeneous. It does not include continuous-fiber reinforced ceramic composites.The test method is applicable to materials with either flat or rising crack growth resistance curves.
