疲劳裂纹尖端 meaning in Chinese
fatigue crack tip
Examples
- The thermal fatigue resistance of al2o3 - 20wt . % tic is the best , it is due to high kic and pore of the material . the pore decrease the stress extension of tip of cracks and delay themal shock fatigue cracks extension . 4
含20wt . tic的复合陶瓷具有高的k _ ( 1c )和较多的孔隙，这些空隙在热震疲劳时降低热震疲劳裂纹尖端的应力集中并阻碍裂纹扩展从而提高了材料的断裂抗力，故其具有最好的抗热疲劳性能。
