Introduction of GB/T 28896-2023

本文件描述了测试金属材料焊接接头应力强度因子（K)、裂纹尖端张开位移[CTOD(δ)]和J积分的试验方法。
本文件是对GB/T 21143的补充，GB/T 21143涵盖了金属材料母材有关断裂韧度测试的试验方法的所有方面，本文件与GB/T 21143配套使用。
本文件适用于测定断裂韧度特征值而不宜用于测定有效的Rcurve（裂纹扩展阻力曲线)，但本文件中试样的加工方法也适用于焊缝金属的Rcurve测定。规定的测试采用的是焊接之后、经机加工缺口并预制疲劳裂纹的金属材料试样，该缺口位于焊缝金属或者热影响区的目标区域，如适用时需要对疲劳裂纹位置的有效性进行评估。
