标准范围

ISO 18756:2003描述了一种试验方法，包括通过弯曲表面裂纹（SCF）法在室温下测定整体陶瓷材料的断裂韧性。本国际标准适用于宏观均匀的单片陶瓷和晶须或颗粒增强陶瓷。它不包括连续纤维增强陶瓷复合材料。本试验方法适用于具有平坦或上升裂纹扩展阻力曲线的材料。

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.
