光弹性法是应力分析的重要方法,它将“应力”这样一个看不见的抽象的概念以条纹图象的形式反映出来。以往一般光弹性试验都是在静载荷情况下来求应力的静态分布。现在我们将一般的光弹性试验与高速摄影结合起来,用分幅和狭缝扫描两种高速摄
Photoelastic method is an important method of stress analysis, it will “stress” such an invisible abstract concept as a striped image reflected. In the past, the general photoelastic test was to find the static distribution of stress under static load. Now we will be the general photoelastic test and high-speed photography combined with the use of framing and slit scanning two high-speed photo
