strain fatigue meaning in Chinese

应变疲劳

Strain fatigue and life estimate of zr - 4 alloy slice
4合金薄片材料的应变疲劳与寿命估算
Analysis results of histogram statistics and section electron microscopic scan technique , are that fracture feature of the cracks of the hbbb is similar and the crack is multi - source strain fatigue one . internal defects of the cast , such as impurities , gas holes , etc , are the main causes for early cracks . the contrast analysis of static strength , model and transient respond on three structures with fem proves that geometrical stress concentration in partial area has influence on early crack , also
利用直方图等统计方法和电镜扫描技术对该抱轴箱体裂纹分析的结果是：抱轴箱体的裂纹断口特征相近，裂纹性质属于多源性低周疲劳裂纹，铸件中的夹杂、气孔等内部缺陷是导致过早裂损的主要原因；利用有限元法对该抱轴箱体三种结构的静强度、模态和动态响应对比分析，证实了局部几何性应力集中对过早裂损也有一定影响。
