摘　　要：利用动光弹法模拟研究在冲击作用下界面上的应力波传播过程 ,利用应力波理论分析了界面上应力波的作用机理 ,证实了界面上存在着能量累积和阻滞能量传递的效应。Complicated changes of stress and strain state were produced on the interface,when subjected to impact load.The transmission of stress wave on the interface was simulated using dynamic photoelastic method. The effect mechanism about stress wave was analyzed with stress wave theory. The interface block effect about energy accumulation and transfusion is confirmed. The relation of stress wave and fringe series was induced using elastic wave motion and stress-optical law.
