通过对带有典型缺陷的薄壁高温合金蜂窝夹层结构进行侧拉伸和侧压缩、平压缩和三点弯曲等力学性能测试,得到了带有不同缺陷形式的结构在不同载荷形式下结构剩余强度随着缺陷尺寸增大的变化规律。得到的结论为薄壁高温合金蜂窝夹层结构的服役可靠性及其损伤容限体系的建立奠定了必要的实验研究基础。
By testing the mechanical properties of thin-walled superalloy honeycomb sandwich with typical flaws, such as side and side compression, flat compression and three-point bending, the residual strength of the structure with different defects in different load forms With the defect size increases the variation. The conclusion obtained lays the necessary experimental research foundation for the service reliability of thin-walled superalloy honeycomb sandwich structure and the establishment of its damage tolerance system.
