中文摘要：
借助有限元数值模拟方法,分析了力学性能参数对镍基合金裂尖应力分布的影响。结果表明随着材料力学性能的变化,镍基合金和氧化膜的裂尖应力分布会发生不同的变化,由此得到了镍基合金和氧化膜的裂尖应力分布规律。
英文摘要：
The effects of mechanical properties parameters on the stress distribution at crack tip of Ni-hased alloy were studied by adopting finite element numerical simulation method. The results show that with the change of material mechanical properties, the stress distribution at crack tip of Ni-based alloy and oxide film generates different changes. Thus, the rule of stress distribution at crack tip of Ni-based alloys and oxide film can he obtained.
