摘要
用动光弹法分析研究了在冲击载荷作用下界面上应力波的传播过程,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作用,并结合弹性波动理论和应力 光学定律导出了波动方程与条纹级数之间的关系式。
Complicated changes of stress and strain state are produced on the interface, when subjected to impact load. The transmission of stress wave on the interface is simulated by dynamic photoelastic method. The effect mechanism about stress wave is analyzed by stress wave theory. The interface block effect about energy accumulation and transfusion is confirmed. The relation of stress wave with fringe series is derived by using elastic wave motion and stress-optical law.
