摘要:

研究了316LN钢焊缝铸态组织在冲击载荷下的断裂行为。针对316LN钢铸态组织中常见的微观组织结构,如等轴状,柱状和树枝状亚晶等组织形态,结合粘聚力有限元方法(CFEM)进行建模,模拟了其裂纹扩展行为并与冲击实验中裂纹的实际扩展路径对比。结果表明,模拟结果给出的裂纹扩展规律与冲击实验结果一致。

Abstract：

The fracture behavior of weld join of steel 316LN by impact test was investigated in terms of macro and micro perspectives, while a numerical model based on cohesive finite element method (CFEM) was presented to describe the effect of microstructure on the fracture behavior of the weld joint of steel 316LN. Based on microstructure images acquired from the experiments, three types of typical microstructure such as equiaxial-, columnar- and dendritic sub-grains were numerically modeled. The crack propagation paths in the three types of microstructure were simulated, and which then were compared with the experimental results. It follows that the observed fracture behavior can be interpreted quite well by the prediction of the simulation.

Key words： metallic materials crack propagation cohesive finite element method sub-grains
