摘要 用三点弯曲多试样方法研究了LD10铝合金的疲劳裂纹扩展速率规律,从而为装备的安全可靠性提供数据依据,利用这些数据可以评估在役装备的剩余寿命。 This paper studied the fatigue crack propagation law on aluminum alloy by the three point bend multi-specimens. It provided the foundation for evaluating the whole structural reliability of the equipment. More over, it can also determine the residual life of the using equipment.
