摘要
利用模拟焊接接头试样三点弯曲试验的方法，就焊接接头强度组配对其断裂性能的影响进行了研究。发现不同的焊接接头强度组配对其断裂韧性和裂纹扩展驱动力有不同程度的影响，在考虑强度组配对焊接接头的断裂性能的影响时，必须从材料的断裂韧性变化和裂纹扩展驱动力变化的两个方面来考虑。
By means of simulated weld joints specimen, the influence of welding strength matching on the fracture property was investigated. It was found that the different strength matching of the welded joints affects both the crack opening driving force and fracture toughness. Both the material fracture toughness and the crack opening driving force must be considered when the influence of welded joint strength matching on the fracture property is analyzed.
