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。
The influence of mechanical properties on the crack tip stress distribution of Ni-based alloy was analyzed by finite element method. The results show that with the change of material mechanical properties, the crack tip stress distribution of Ni-based alloy and oxide film changes in different ways, and the crack tip stress distribution of Ni-based alloy and oxide film is obtained.
