1) pre-damage
预损伤
1.
The effect of different pre-damage on fracture behavior of lamellar TiAl alloys by means of tensile tests at various unloading loads was studied.
通过对层状TiAl基合金进行拉伸卸载试验,研究了不同预损伤对层状TiAl基合金断裂行为的影响。
2.
It is found that the areal density of cracks increases with the increasing of the degree of pre-damage,and the fracture process of plate tensile fracture is consistent with that of tensile-unloadingfracture,the fracture energy per unit area remains basically unchanged,It means that pre-damage has no effect on the fracture process and final fracture properties of lame.
结合宏观试验结果与断口分析发现,随着预损伤程度的增加,裂纹面密度增大;平板拉伸直接断裂试样的断裂过程与拉伸-卸载后拉断试样的断裂过程一致,单位面积断裂功基本不变。
