本文通过16M_nR 低温延性断裂韧度的测试,提出了在低温下确定 J_(IC)的简便方法,并把低温下确定 J—R 曲线与确定 J_(IC)统一起来考虑。
In this paper, we propose a simple and convenient method to determine J IC at low temperature by testing low ductility fracture toughness of 16M_nR and considering the determination of J-R curve and determination of J IC at low temperature.
