中文名称：细陶瓷 （高级陶瓷、高技术陶瓷） 人字形凹槽横梁（CNB）法测定整体式陶瓷在室温下的断裂韧度的试验方法

英文名称：Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for fracture toughness of monolithic ceramics at room temperature by chevron-notched beam (CNB) method

发布日期：2005-06

标准范围

This International Standard specifies a test method for determining the fracture toughness of monolithic ceramic materials at room temperature by the chevron-notched beam (CNB) method.This International Standard is applicable to monolithic ceramics and whisker- or particulate-reinforced ceramics that are regarded as macroscopically homogeneous. It is not applicable to continuous-fibre reinforced ceramic composites.This International Standard is usually applicable to ceramic materials with a fracture toughness less than about 12 MPa(m). The test method is applicable to materials with a flat crack-growth resistance curve and may be applicable to materials with a rising crack-growth resistance curve (R-curve).
