| 摘 要： | 在应力波传播过程中,半无限平面的聚酯模型在一个截面上的主应力分布解被实验所确定。应力波由摆式重锤的冲击所产生。应用两个外部适当的触发装置触发一个双脉冲红宝石激光器(0.5焦耳/每脉冲)。模型的一个表面做成全反射面,利用对这个表面的反射式全息干涉法和通过模型的另一表面的反射式光弹性法可以记录冲击后不同时间延迟的等和线与等差线条纹图。 |
| 关 键 词： | 反射全息干涉 反射光弹性法 应力波传播 |

| Abstract: | The principal stress distribution on a section of a palyester model of asemi-infinite plate during the propagation of a stress wave has been determined experimentally. The stress pulse was generated by the impact of a pendulum hammer. Two external suitable trigger mechanism was used to trigger a double-pulse Ruby Laser (0.5 Joule per pulse) at predetermined intervals. One surface of the model was made fully reflecting so that by means of refective holo-interferometry of that surface and reflective photoelasticity through the other surface of the model the isopachic and isochromatic fringe patterns were recorded at different time delays after impact. |
