The effects of strength mis-matching and specimen geometry on the resistance behavior to ductile crack growth for welded joint were conducted by 3-D FE analysis considering the micro-plastic damage.
通过考虑材料微观塑性损伤，定量研究了焊接接头中强度匹配、试件几何形状对接头抗延性裂纹扩展行为的影响。
It is shown that the proposed ductile fracture model can accurately and effectively predict the whole damage process of ductile metals including crack initiation, propagation and final fracture.
结果表明，该模型可很好地预测延性金属材料自裂纹萌生、扩展直至完全断裂的全过程。
