《GB/T 21143-2014金属材料准静态断裂韧度的统一试验方法》由TC183（全国钢标准化技术委员会）归口，TC183SC4（全国钢标准化技术委员会力学及工艺性能试验方法分会）执行，主管部门为中国钢铁工业协会。
本标准规定了均匀金属材料在承受准静态加载时断裂韧度、裂纹尖端张开位移、J 积分和阻力曲线的试验方法。试样有缺口,采用疲劳的方法预制裂纹,在缓慢增加位移量的条件下进行试验。

Scope

This standard specifies the test methods for fracture toughness, crack tip opening displacement, J-integral and resistance curves of homogeneous metallic materials subjected to quasi-static loading. The sample has a gap, and the fatigue method is used to prefabricate the crack, and the test is carried out under the condition of slowly increasing the displacement.
