1)过冷度对裂纹扩展影响显著,过冷度越小(即温度越高),裂纹扩展越快且分叉越多。
There is significant influence of the supercooling degree on the crack propagation. The smaller the supercooling degree is (that is to say, the higher the temperature is), the faster the crack propagation is and the more crack branching is.
2)裂纹在扩展过程中,体系能力不断降低,当裂纹出现分叉时,体系能量降低的更快。
The results showed that the system energy continously decreased in the process of cracks propagation. The system energy decreased much faster when the cracks started to branch off.
Hope it helps you!!!! Good Luck. |
