摘要
对大型焊接结构焊缝进行了裂纹尖端张开位移(CTOD)断裂韧度试验,测试了其焊缝的CTOD特征值,得出相应的结论。
Based on BS7448 fracture toughness test experiment standard and DNV-OS-C401, the analysis of the welded seam of structure is extended to three point bending specimen with a center crack were carried out, the CTOD value of the welded zone were obtain.
