本文用动态光弹性法研究了冲击荷载作用下开口圆环的动应力分布，比较了动态和静态荷载作用下应力分布的差异，并描述了应力波在开口圆环内的传播过程。
In this paper, the dynamic photoelasticity method is used to study the dynamic stress distribution of the open ring under impact load. The difference of stress distribution under dynamic and static loads is compared. The propagation of stress wave in the open ring is also described.
