摘要基于材料微观损伤模型，采用三维有限元数值方法，定量研究了焊接接头中强度匹配、试件几何型式对接头抗延性裂纹扩展阻力特性的影响。 - : 36 < kth < 37 mpa / m3 / 2 , 42 < kih < 44mpa / m3 / 2 , 51 < kc < 52 mpa / m3 / 2 through the sem fractography , it is know that the susceptibility to brittle failure at room temperature is more than below 100 ? . and the susceptibility to brittle failure increase with hydrogen increasing , under the sustained loading , ductile cracking appears . the quantity of brittle cracking is more with crack growth
T44mpa m ‘ q ， sl lt52mpa in ’ ”断口分析表明，该合金充氢后其室温时的氢脆敏感性大于100oc时的氢脆敏感性；且随氢含量升高，氢脆敏感性增加：在恒载荷的作用下，该合金裂二纹开始扩展时显示的是韧性起裂；随裂纹增长，试样脆性断裂的比例增大。 - Firstly , the parameters controlling ductile crack growth are gotten from the resistance curve result of standard 3 point bending specimen , then the resistance curves of the tension specimen for the welded joint with different strength mis - matching are predicted based on the cell model
首先由标准三点弯曲试件的阻力曲线，得出反映材料微观损伤的特殊单元模型控制参量，再根据该参量对不同接头强度匹配下双边缺口拉伸试件的阻力曲线进行了定量预测，其结果与试验结果相当吻合。
