对自由ＡＲＡＬＬ层板和两种预应力ＡＲＡＬＬ层板的冲击损伤机理、冲击损伤在疲劳过程中的扩展进行了表面观察与无损检测分析，建立了层板冲击后的疲劳累积损伤模型，探讨了预应力对ＡＲＡＬＬ层板冲击后疲劳性能的影响。
The impact damage mechanism of free ARALL laminates and two kinds of prestressed ARALL laminates, the surface observation and non-destructive testing of the extension of impact damage in fatigue process were established, and the fatigue cumulative damage model after laminar impact was established. Effect of Stress on Fatigue Performance of ARALL Laminates after Shock.
